Add manager ability to send the cmd line and working directory instead.

* Refactors TerminalApp into two projects: 
  - TerminalAppLib, which builds a .lib, and includes all the code
  - TerminalApp, which builds a dll by linking the lib
* Adds a TerminalApp.Unit.Tests project
  - Includes the ability to test cppwinrt types we've authored using a SxS manifest for unpackaged winrt activation
  - includes the ability to test types with XAML content using an appxmanifest
* Adds a giant doc explaining how this was all done. Really, just go read that doc, it'll really help you understand what's going on in this PR.

-------------------------
These are some previous commit messages. They may be helpful to future readers.

* Start adding unittests for json parsing, end up creating a TerminalAppLib project to make a lib. See #1042

* VS automatically did this for me

* This is a dead end

  I tried including the idl-y things into the lib, but that way leads insanity

  If you want to make a StaticLibrary, then suddenly the winrt toolchain forgets
  that ProjectReferences can have winmd's in them, so it won't be able to
  compile any types from the referenced projects. If you instead try to manually
  reference the types, you'll get duplicate types up the wazoo, which of course
  is insane, since we're referencing them the _one_ time

* Yea just follow #1042 on github for status

  So current state:

  1. If you try to add a `Reference` to all of MUX.Markup, TerminalControl and
     TerminalSettings, then mdmerge will complain about all   the types from
     TerminalSettings being defined twice. In this magic scenario, the
     dependencies of TerminalControl are used directly   for some reason:

```
  12>    Load input metadata file ...OpenConsole\x64\Debug\TerminalSettings\Microsoft.Terminal.Settings.winmd.
  12>    Load input metadata file ...OpenConsole\x64\Debug\TerminalControl\Microsoft.Terminal.Settings.winmd.
  12>    Load input metadata file ...OpenConsole\x64\Debug\TerminalControl\Microsoft.Terminal.TerminalConnection.winmd.
  12>    Load input metadata file ...OpenConsole\x64\Debug\TerminalControl\Microsoft.Terminal.TerminalControl.winmd.
  12>    Load input metadata file ...OpenConsole\x64\Debug\Microsoft.UI.Xaml.Markup\Microsoft.UI.Xaml.Markup.winmd.
```

  2. If you don't add a `Reference` TerminalControl, then it'll complain about
     being unable to find the type TitleChangedEventArgs,   which is defined in
     TerminalControl.

  3. If you don't add a `Reference` TerminalSettings, then it'll complain about
     being unable to find the type KeyChord and other   types from
     TerminalSettings. In this scenario, it doesn't recurse on the other
     dependencies from TerminalControl for whatever   reason.

  4. If you instead try to add all 3 as a `ProjectReference`, then it'll
     complain about being unable to find TitleChangedEventArgs,   as in 2.
     Presumably, it;ll have troubles with the other types too, as none of the 3
     are actually included in the midlrt.rsp file.

  5. If you add all 3 as a `ProjectReference`, then also add TerminalControl as
     a `Reference`, you'll get a `MIDL2011: [msg]  unresolved type declaration
     Microsoft.UI.Xaml.Markup.XamlApplication`

  6. If you add all 3 as a `ProjectReference`, then also add TerminalControl AND
     MUX.Markup as a `Reference`, you'll get the same   result as 3.

* what if we just don't idl

  This seems to compile

* This compiles but I broke the MUX resources

  look at the App.xaml change. in this changelist. That's what's broken right now. Lets fix that!

* lets do this

    If I leave the MUX nuget out of the project, I'll get a compile error in
    App.xaml:

    ```
    ...OpenConsole\src\cascadia\TerminalApp\App.xaml(21,40): XamlCompiler error WMC0001: Unknown type 'XamlControlsResources' in XML namespace 'using:Microsoft.UI.Xaml.Controls'
    ```

    If I add it back to the project, it works

* Some cleanup from the previous commit

* This is busted again.

  Doing a clean build didn't work.

    A clean rebuild of the project, paired with some removal of dead code
    revealed a problem with what I have so far.

    TerminalAppLib depends on the generation of two headers,
    `AppKeyBindings.g.h` and `App.g.h`, as those define some of bits of the
    winrt types. They're needed to be able to compile the implementations.
    Presumably that's not getting generated by the lib project, because the dll
    project is the one to generate that file.

    So we need to move the idl's to the lib project. This created maddness,
    because of course the Duplicate Type thing. The solution to that is to
    actually mark the winrt DLLs that we're chaining up through us as

    ```
        <Private>false</Private>
        <CopyLocalSatelliteAssemblies>false</CopyLocalSatelliteAssemblies>
    ```

    This will prevent them from getting double-included.

    This still doesn't work however, since
    ```
    app.cpp(40): error C2039: 'XamlMetaDataProvider': is not a member of 'winrt::TerminalApp'
    error C3861: 'XamlMetaDataProvider': identifier not found
    ```

    So we need to figure that out. The dll project is still generating the right
    header, so lets look there.

* Move the xaml stuff to the lib

  This compiles, but when we launch, we fail to load the tabviewcontrol
  resources again. So that's not what you want. Why is it not included?

* It works again!

  * Use the pri, xbf files from TerminalAppLib, not TerminalApp
  * Manually make TerminalApp include a reference to TerminalAppLib's
    TerminalApp.winmd. This will force the build to copy TerminalApp.winmd to
    TerminalApp/, which WindowsTerminal needs to be able to ProjectReference the
    TerminalApp project (it's expecting it to have a winmd)
  * Remove the module.g.cpp from TerminalApp, and move to TerminalAppLib. The
    dll doesn't do any codegen anymore.

* Agressively clean up these files

* Clean up unnecessary includes in the dll pch.h

* This does NOT work.

  The WindowsxamlManager call crashes. I'm thinking it has to do with activation
  of winrt types from a dll.

  Email out to @Austin-Lamb to see if he can assist

* This gets our cppwinrt types working, but xaml islands is still broken

* Split the tests apart, so they aren't insane

* These are the magic words to make xaml islands work

* All this witchcraft is necessary to make XAML+MUX work right

* Clean this up a bit and add comments

* Create an enormous doc explaining this madness

* Unsure how this got changed.

* Trying to get the CI build to work again.

  This resolves the MUX issue. We need to manually include it, because their package's target doesn't mark it as CopyLocalSatelliteAssemblies=false, Private=false.

  However, the TerminalApp project is still able to magically reason that the TerminalAppLib project should be included in the MdMerge step, because it think's it's a `GetCppWinRTStaticProjectReferences` reference.

* Update cppwinrt to the latest version - this fixes the MSBuild

  * I still need to re-add the KeyModifiers checks from TermControl. I think
    this update broke `operator&` for that enum.
  * There needs to be some cleanup obviously
  * The doc should be updated as well

* Clean up changes from cppwinrt update

* Try doing this, even though it seems wrong

* Lets try this (press x to doubt)

* Clean up vcxproj file, and remove appxmanifest change from previous commit

* Update to the latest TAEF release, maybe that'll work

* Let's try a prerelease version, shall we?

* Add notes about TAEF package, comment out tests

* Format the code

* Hopefully fix the arm64 and x86 builds

  also a typo

* Fix PR nits

* Fix some bad merge conflicts

* Some cleanup from the merge

* Well I was close to getting the merge right

* I believe this will fix CI

* Apply suggestions from code review

Co-Authored-By: Carlos Zamora <carlos.zamora@microsoft.com>

* These definitely need to be fixed

* Try version detecting in the test

  IDK if this will build, I'm letting the CI try while I clean rebuild locally

* Try blindly updating to the newest nuget version

* Revert "Try blindly updating to the newest nuget version"

This reverts commit b72bd9eb73.

* We're just going to see if these work in CI with this change

* Comment the tests back out. Windows Server 2019 is 10.0.17763.557

* Remove the nuget package

  We don't need this package anymore now that we're hosting it

* Okay this _was_ important

+# Panes in the Windows Terminal
+
+## Abstract
+
+Panes are an abstraction by which the terminal can display multiple terminal
+instances simultaneously in a single terminal window. While tabs allow for a
+single terminal window to have many terminal sessions running simultaneously
+within a single window, only one tab can be visible at a time. Panes, on the
+other hand, allow a user to have many different terminal sessions visible to the
+user within the context of a single window at the same time. This can enable
+greater productivity from the user, as they can see the output of one terminal
+window while working in another.
+
+This spec will help outline the design of the implementation of panes in the
+Windows Terminal.
+
+## Inspirations
+
+Panes within the context of a single terminal window are not a new idea. The
+design of the panes for the Windows Terminal was heavily inspired by the
+application `tmux`, which is a commandline application which acts as a "terminal
+multiplexer", allowing for the easy managment of many terminal sessions from a
+single application.
+
+Other applications that include pane-like functionality include (but are not
+limited to):
+
+* screen
+* terminator
+* emacs & vim
+* Iterm2
+
+## Design
+
+The architecture of the Windows Terminal can be broken into two main pieces:
+Tabs and Panes. The Windows Terminal supports _top-level_ tabs, with nested
+panes inside the tabs. This means that there's a single strip of tabs along the
+application, and each tab has a set of panes that are visible within the context
+of that tab.
+
+Panes are implemented as a binary tree of panes. A Pane can either be a leaf
+pane, with it's own terminal control that it displays, or it could be a parent
+pane, where it has two children, each with their own terminal control.
+
+When a pane is a parent, its two children are either split vertically or
+horizontally. Parent nodes don't have a terminal of their own, they merely
+display the terminals of their children.
+
+ * If a Pane is split vertically, the two panes are seperated by a vertical
+   split, as to appear side-by-side. Think `[|]`
+ * If a Pane is split horizontally, the two panes are split by a horizontal
+   separator, and appear above/below one another. Think `[-]`.
+
+As additional panes are created, panes will continue to subdivide the space of
+their parent. It's up to the parent pane to control the sizing and display of
+it's children.
+
+### Example
+
+We'll start by taking the terminal and creating a single vertical split. There
+are now two panes in the terminal, side by side. The original terminal is `A`,
+and the newly created one is `B`. The terminal now looks like this:
+
+```
+  +---------------+
+  |       |       |    1: parent [|]
+  |       |       |    ├── 2: A
+  |       |       |    └── 3: B
+  |   A   |   B   |
+  |       |       |
+  |       |       |
+  |       |       |
+  +---------------+
+```
+
+Here, there are actually 3 nodes: 1 is the parent of both 2 and 3. 2 is the node
+containing the `A` terminal, and 3 is the node with the `B` terminal.
+
+
+We could now split `B` in two horizontally, creating a third terminal pane `C`.
+
+```
+  +---------------+
+  |       |       |    1: parent [|]
+  |       |   B   |    ├── 2: A
+  |       |       |    └── 3: parent [-]
+  |   A   +-------+        ├── 4: B
+  |       |       |        └── 5: C
+  |       |   C   |
+  |       |       |
+  +---------------+
+```
+
+Node 3 is now a parent node, and the terminal `B` has moved into a new node as a
+sibling of the new terminal `C`.
+
+We could also split `A` in horizontally, creating a fourth terminal pane `D`.
+
+```
+  +---------------+
+  |       |       |    1: parent [|]
+  |   A   |   B   |    ├── 2: parent [-]
+  |       |       |    |   ├── 4: A
+  +-------+-------+    |   └── 5: D
+  |       |       |    └── 3: parent [-]
+  |   D   |   C   |        ├── 4: B
+  |       |       |        └── 5: C
+  +---------------+
+```
+
+While it may appear that there's a single horizonal separator and a single
+vertical separator here, that's not actually the case. Due to the tree-like
+structure of the pane splitting, the horizontal splits exist only between the
+two panes they're splitting. So, the user could move each of the horizontal
+splits independently, without affecting the other set of panes. As an example:
+
+```
+  +---------------+
+  |       |       |
+  |   A   |       |
+  +-------+   B   |
+  |       |       |
+  |   D   |       |
+  |       +-------+
+  |       |   C   |
+  +---------------+
+```
+
+### Creating a pane
+
+In the basic use case, the user will decide to split the currently focused pane.
+The currently focused pane is always a leaf, because as parent's can't be
+focused (they don't have their own terminal). When a user decides to add a new
+pane, the child will:
+
+ 1. Convert into a parent
+ 2. Move its terminal into its first child
+ 3. Split its UI in half, and display each child in one half.
+
+It's up to the app hosting the panes to tell the pane what kind of terminal in
+wants created in the new pane. By default, the new pane will be created with the
+default settings profile.
+
+### While panes are open
+
+When a tab has multiple panes open, only one is the "active" pane. This is the
+pane that was last focused in the tab. If the tab is the currently open tab,
+then this is the pane with the currently focused terminal control. When the user
+brings the tab into focus, the last focused pane is the pane that should become
+focused again.
+
+The tab's state will be updated to reflect the state of it's focused pane. The
+title text and icon of the tab will reflect that of the focused pane. Should the
+focus switch from one pane to another, the tab's text and icon should update to
+reflect the newly focused control. Any additional state that the tab would
+display for a single pane should also be reflected in the tab for a tab with
+multiple panes.
+
+While panes are open, the user should be able to move any split between panes.
+In moving the split, the sizes of the terminal controls should be resized to
+match.
+
+### Closing a pane
+
+A pane can either be closed by the user manually, or when the terminal it's
+attached to raises its ConnectionClosed event. When this happens, we should
+remove this pane from the tree. The parent of the closing pane will have to
+remove the pane as one of it's children. If the sibling of the closing pane is a
+leaf, then the parent should just take all of the state from the remaining pane.
+This will cause the remaining pane's content to expand to take the entire
+boundaries of the parent's pane. If the remaining child was a parent itself,
+then the parent will take both the children of the remaining pane, and make them
+the parent's children, as if the parent node was taken from the tree and
+replaced by the remaining child.
+
+## Future considerations
+
+The Pane implementation isn't complete in it's current form. There are many
+additional things that could be done to improve the user experience. This is by
+no means a comprehensive list.
+
+* [ ] Panes should be resizable with the mouse. The user should be able to drag
+  the separator for a pair of panes, and have the content between them resize as
+  the separator moves.
+* [ ] There's no keyboard shortcut for "ClosePane"
+* [ ] The user should be able to configure what profile is used for splitting a
+  pane. Currently, the default profile is used, but it's possible a user might
+  want to create a new pane with the parent pane's profile.
+* [ ] There should be some sort of UI to indicate that a particular pane is
+  focused, more than just the blinking cursor. `tmux` accomplishes this by
+  colorizing the separators adjacent to the active pane. Another idea is
+  displaying a small outline around the focused pane (like when tabbing through
+  controls on a webpage).
+* [ ] The user should be able to navigate the focus of panes with the keyboard,
+  instead of requiring the mouse.
+* [ ] The user should be able to zoom a pane, to make the pane take the entire
+  size of the terminal window temporarily.
+* [ ] A pane doesn't necessarily need to host a terminal. It could potentially
+  host another UIElement. One could imagine enabling a user to quickly open up a
+  Browser pane to search for a particular string without needing to leave the
+  terminal.
+
+## Footnotes
+
+### Why not top-level panes, and nested tabs?
+
+If each pane were to have it's own set of tabs, then each pane would need to
+reserve screen real estate for a row of tabs. As a user continued to split the
+window, more and more of the screen would be dedicated to just displaying a row
+of tabs, which isn't really the important part of the application, the terminal
+is.
+
+Additionally, if there were top-level panes, once the root was split, it would
+not be possible to move a single pane to be the full size of the window. The
+user would need to somehow close the other panes, to be able to make the split
+the size of the dull window.
+
+One con of this design is that if a control is hosted in a pane, the current
+design makes it hard to move out of a pane into it's own tab, or into another
+pane. This could be solved a number of ways. There could be keyboard shortcuts
+for swapping the positions of tabs, or a shortcut for both "zooming" a tab
+(temporarily making it the full size) or even popping a pane out to it's own
+tab. Additionally, a right-click menu option could be added to do the
+aformentioned actions. Discoverability of these two actions is not as high as
+just dragging a tab from one pane to another; however, it's believed that panes
+are more of a power-user scenario, and power users will not neccessarily be
+turned off by the feature's discoverability.

+# Getting TAEF unittests to work with a C++/WinRT XAML Islands application
+
+* __Author__: Mike Griese @zadjii-msft
+* __Created on__: 2019-06-06
+
+
+So you've built a Win32 application that uses XAML Islands to display it's UI
+with C++/WinRT. How do you go about adding unittests to this application? I'm
+going to cover the steps that I took to get the Windows Terminal updated to be
+able to test not only our C++/WinRT components, but also pure c++ classes that
+were used in the application, and components that used XAML UI elements.
+
+## Prerequisites
+
+Make sure you're using at least the 2.0.190605.7 version of the CppWinRT nuget
+package. Prior to this version, there are some bugs with C++/WinRT's detection
+of static lib dependencies. You might be able to get your build working with
+Visual Studio on earlier versions, but not straight from MsBuild.
+
+Also, if you're going to be running your tests in a CI build of some sort, make
+sure that your tests are running on a machine running at least Windows 18362. If
+your CI isn't running that version, then this doesn't matter at all.
+
+Furthermore, you may need an updated TAEF package as well. Our CI uses the TAEF
+VsTest adapter to allow ADO to run TAEF tests in CI. However, there's a bug in
+the tests adapter that prevents it from running tests in a UAP context. The
+`10.38.190605002` TAEF is the most recent release at the time of writing,
+however, that doesn't have the fix necessary. Fortunately, the TAEF team was
+kind enough to prototype a fix for us, which is the version
+`10.38.190610001-uapadmin`, which we're using in this repo until an official
+release with the fix is available.
+
+## Move the C++/WinRT implementation to a static lib
+
+By default, most (newly authored) C++/WinRT components are authored as a dll
+that can be used to activate your types. However, you might have other classes
+in that binary that you want to be able to test, which aren't winrt types. If
+the implementation is sitting in a DLL, it'll be hard to write a TAEF unittest
+dll that can call the pure c++ types you've defined.
+
+The first thing you're going to need to do is move the implementation of your
+winrt component from a dll to a static lib. Once you have the static lib, we'll
+be able to link it into the dll you were previously producing, as well as being
+able to link it into the dll we'll be using to test the types. Once this is
+complete, your dll project will exist as little more than some extra packaging
+for your new lib, as all your code will be built by the lib.
+
+To aid in this description, I'll be referring to the projects that we changed.
+The dll project we changed to a lib was the `TerminalApp` project. From it, we
+created a new `TerminalAppLib` project, and changed `TerminalApp` to create a
+dll by linking the lib `TerminalAppLib` produced.
+
+### Create the static lib project
+
+We'll start by creating a new static lib project. The easiest way to do this is
+by copying your existing dll `vcxproj` file into a new file. Make sure to change
+the `ProjectGuid` and to add the new project to your `.sln` file. Then, change
+the `ConfigurationType` to `StaticLibrary`. This Lib should be responsible for
+building all of your headers, `.cpp` files, `.idl`s for your winrt types, and
+any `.xaml` files you might have.
+
+You'll likely need to place this new file into a separate directory from the
+existing dll project, as C++/WinRT uses the project directory as the root of the
+intermediate build tree. Each directory should only have one `.vcxproj` file in
+it. For the Terminal project, we created a subdirectory `lib/` underneath
+`TerminalApp/`, and updated the `Include` paths to properly point at the
+original files. You could alternatively put all the source in one directory, and
+have separate `dll/` and `lib/` subdirectories from the source that are solely
+responsible for building their binary.
+
+At this point, you might face some difficulty including the right wimnd
+references, especially from other C++/WinRT dependencies for this project that
+exist in your solution. I don't know why, but I had a fair amount of difficulty
+using a `ProjectReference` from a C++/WinRT StaticLibrary to another C++/WinRT
+project in my solution. If you're referring to any other projects, you'll need
+to set up a reference to their built `.winmd`'s manually.
+
+As an example, here's how we've added a reference to the `TerminalSettings`
+project from our `TerminalAppLib` project:
+
+```xml
+  <ItemGroup>
+    <!-- Manually add references to each of our dependent winmds. Mark them as
+    private=false and CopyLocalSatelliteAssemblies=false, so that we don't
+    propogate them upwards (which can make referencing this project result in
+    duplicate type definitions)-->
+
+    <Reference Include="Microsoft.Terminal.Settings">
+      <HintPath>$(SolutionDir)$(Platform)\$(Configuration)\TerminalSettings\Microsoft.Terminal.Settings.winmd</HintPath>
+      <IsWinMDFile>true</IsWinMDFile>
+      <Private>false</Private>
+      <CopyLocalSatelliteAssemblies>false</CopyLocalSatelliteAssemblies>
+    </Reference>
+  </ItemGroup>
+```
+
+The `HintPath` may be different depending on your project structure - verify
+locally the right path to the `.winmd` file you're looking for.
+
+Notably, you'll also need to put a `pch.h` and `pch.cpp` in the new lib's
+directory, and use them instead of the `pch.h` used by the dll. C++/WinRT will be
+very angry with you if you try to use a `pch.h` in another directory. Since
+we're putting all the code into the static lib project, take your existing
+`pch.h` and move it to the lib project's directory and create an empty `pch.h`
+in the dll project's directory.
+
+### Update the dll project
+
+Now that we havea lib that builds all your code, we can go ahead and tear out
+most of the dead code from the old dll project. Remove all the source files from
+the dll's `.vcxproj` file, save for the `pch.h` and `pch.cpp` files. You _may_
+need to leave the headers for any C++/WinRT types you've authored in this project
+- I'm not totally sure it's necessary.
+
+Now, to link the static lib we've created. For whatever reason, adding a
+`ProjectReference` to the static lib doesn't work. So, we'll need to manually
+link the lib from the lib project. You can do that by adding the lib's output
+dir to your `AdditionalLibraryDirectories`, and adding the lib to your
+`AdditionalDependencies`, like so:
+
+```xml
+  <ItemDefinitionGroup>
+    <Link>
+      <!-- Manually link with the TerminalAppLib.lib we've built. -->
+      <AdditionalLibraryDirectories>$(SolutionDir)\$(Platform)\$(Configuration)\TerminalAppLib;%(AdditionalLibraryDirectories)</AdditionalLibraryDirectories>
+
+      <AdditionalDependencies>TerminalAppLib.lib;%(AdditionalDependencies)</AdditionalDependencies>
+    </Link>
+  </ItemDefinitionGroup>
+```
+
+We are NOT adding a reference to the static lib project's .winmd here. As of the
+2.0.190605.7 CppWinRT nuget package, this is enough for MsBuild and Visual
+Studio to be able to determine that the static lib's  `.winmd` should be included
+in this package.
+
+At this point, you might have some mdmerge errors, which complain about
+duplicate types in one of your dependencies. This might especially happen if one
+of your dependencies (ex `A.dll`) is also a dependency for one of your _other_
+dependencies (ex `B.dll`). In this example, your final output project `C.dll`
+depends on both `A.dll` and `B.dll`, and `B.dll` _also_ depends on `A.dll`. If
+you're seeing this, I recommend adding `Private=false` and
+`CopyLocalSatelliteAssemblies=false` to your dependent dlls. In this example,
+add similar code to `B.dll`:
+
+```xml
+    <ProjectReference Include="$(SolutionDir)src\cascadia\TerminalSettings\TerminalSettings.vcxproj">
+      <Private>false</Private>
+      <CopyLocalSatelliteAssemblies>false</CopyLocalSatelliteAssemblies>
+    </ProjectReference>
+```
+
+where `TerminalSettings` is your `A.dll`, which is included by both `B` and `C`.
+
+We additionally had an `.exe` project that was including our `TerminalApp`
+project, and all its `.xbf` and `.pri` files. If you have a similar project
+aggregating all your resources, you might need to update the paths to point to
+the new static lib project.
+
+At this point, you should be able to rebuild your solution, and everything
+should be working just the same as before.
+
+
+## Add TAEF Tests
+
+Now that you have a static library project, you can start building your unittest
+dll. Start by creating a new directory for your unittest code, and creating a
+`.vcxproj` for a TAEF unittest dll. For the Terminal solution, we use the TAEF
+nuget package `Taef.Redist.Wlk`.
+
+### Referencing your C++/WinRT static lib
+
+This step is the easiest. Add a `ProjectReference` to your static lib project,
+and your lib will be linked into your unittest dll.
+
+```xml
+    <ProjectReference Include="$(SolutionDir)\src\cascadia\TerminalApp\lib\TerminalAppLib.vcxproj" />
+```
+
+Congratulations, you can now instantiate the pure c++ types you've authored in
+your static lib. But what if you want to test your C++/WinRT types too?
+
+### Using your C++/WinRT types
+
+To be able to instantiate your C++/WinRT types in a TAEF unittest, you'll need
+to rely on a new feature to Windows in version 1903 which enables unpackaged
+activation of WinRT types. To do this, we'll need to author a SxS manifest that
+lists each of our types, and include it in the dll, and also activate it
+manually from TAEF.
+
+#### Creating the manifest
+
+First, you need to create a manifest file that lists each dll your test depends
+upon, and each of the types in that dll. For example, here's an excerpt from the
+Terminal's manifest:
+
+```xml
+<?xml version="1.0" encoding="utf-8" standalone="yes"?>
+<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
+  <file name="TerminalSettings.dll" hashalg="SHA1">
+    <activatableClass name="Microsoft.Terminal.Settings.KeyChord" threadingModel="both" xmlns="urn:schemas-microsoft-com:winrt.v1"></activatableClass>
+    <activatableClass name="Microsoft.Terminal.Settings.TerminalSettings" threadingModel="both" xmlns="urn:schemas-microsoft-com:winrt.v1"></activatableClass>
+  </file>
+  <file name="TerminalApp.dll" hashalg="SHA1">
+    <activatableClass name="TerminalApp.App" threadingModel="both" xmlns="urn:schemas-microsoft-com:winrt.v1"></activatableClass>
+    <activatableClass name="TerminalApp.AppKeyBindings" threadingModel="both" xmlns="urn:schemas-microsoft-com:winrt.v1"></activatableClass>
+    <activatableClass name="TerminalApp.XamlmetaDataProvider" threadingModel="both" xmlns="urn:schemas-microsoft-com:winrt.v1"></activatableClass>
+  </file>
+</assembly>
+```
+
+Here we have two dlls that we depend upon, `TerminalSettings.dll` and
+`TerminalApp.dll`. `TerminalSettings` implements two types,
+`Microsoft.Terminal.Settings.KeyChord` and
+`Microsoft.Terminal.Settings.TerminalSettings`.
+
+#### Linking the manifest to the test dll
+
+Now that we have a manifest file, we need to embed it in your unittest dll. This
+is done with the following properties in your `vcxproj` file:
+
+```xml
+  <PropertyGroup>
+    <GenerateManifest>true</GenerateManifest>
+    <EmbedManifest>true</EmbedManifest>
+  </PropertyGroup>
+  <ItemGroup>
+    <Manifest Include="TerminalApp.Unit.Tests.manifest" />
+  </ItemGroup>
+```
+where `TerminalApp.Unit.Tests.manifest` is the name of your manifest file.
+
+Additionally, you'll need to binplace the manifest _adjacent to your test
+binary_, so TAEF can find it at runtime. I've done this in the following way,
+though I'm sure there's a better way:
+
+```xml
+  <ItemDefinitionGroup>
+    <PostBuildEvent>
+      <!-- Manually copy the manifest to our outdir, because the test will need
+      to find it adjacent to us. -->
+      <Command>
+        (xcopy /Y &quot;$(OpenConsoleDir)src\cascadia\ut_app\TerminalApp.Unit.Tests.manifest&quot; &quot;$(OutDir)\TerminalApp.Unit.Tests.manifest*&quot; )
+      </Command>
+    </PostBuildEvent>
+  </ItemDefinitionGroup>
+```
+
+#### Copying your dependencies
+
+Additionally, any dlls that implement any types your test is dependent upon will
+also need to be in the output directory for the test. Manually copy those DLLs
+to the tests' output directory too. The updated `PostBuildEvent` looks like
+this:
+
+```xml
+  <ItemDefinitionGroup>
+    <PostBuildEvent>
+      <Command>
+        echo OutDir=$(OutDir)
+        (xcopy /Y &quot;$(SolutionDir)src\cascadia\ut_app\TerminalApp.Unit.Tests.manifest&quot; &quot;$(OutDir)\TerminalApp.Unit.Tests.manifest*&quot; )
+
+        (xcopy /Y &quot;$(SolutionDir)$(Platform)\$(Configuration)\TerminalConnection\TerminalConnection.dll&quot; &quot;$(OutDir)\TerminalConnection.dll*&quot; )
+        (xcopy /Y &quot;$(SolutionDir)$(Platform)\$(Configuration)\TerminalSettings\TerminalSettings.dll&quot; &quot;$(OutDir)\TerminalSettings.dll*&quot; )
+        (xcopy /Y &quot;$(SolutionDir)$(Platform)\$(Configuration)\TerminalControl\TerminalControl.dll&quot; &quot;$(OutDir)\TerminalControl.dll*&quot; )
+      </Command>
+    </PostBuildEvent>
+  </ItemDefinitionGroup>
+```
+
+Again, verify the correct paths to your dependant C++/WinRT dlls, as they may be
+different than the above
+
+#### Activating the manifest from TAEF
+
+Now that the manifest lives adjacent to your test dll, and all your dependent
+dlls are also adjacent to the unittest dll, there's only one thing left to do.
+TAEF will not use your dll's manifest by default, so you'll need to add a
+property to your test class/method to tell TAEF to do so. You can do this with
+the following:
+
+```c++
+class SettingsTests
+{
+    // Use a custom manifest to ensure that we can activate winrt types from
+    // our test. This property will tell taef to manually use this as the
+    // sxs manifest during this test class. It includes all the C++/WinRT
+    // types we've defined, so if your test is crashing for an unknown
+    // reason, make sure it's included in that file.
+    BEGIN_TEST_CLASS(SettingsTests)
+        TEST_CLASS_PROPERTY(L"ActivationContext", L"TerminalApp.Unit.Tests.manifest")
+    END_TEST_CLASS()
+
+    // Other Test code here
+}
+```
+
+Now, if you try to add any test methods that instantiate WinRT types you've
+authored, they'll work. That is of course, so long as they don't use XAML. If
+you want to use any XAML types, then you'll have to keep reading.
+
+### Using Xaml Types (with XAML Islands)
+
+To be able to instatiate XAML types in your unittest, we'll need to make use of
+the [XAML Hosting
+API](https://docs.microsoft.com/en-us/windows/apps/desktop/modernize/using-the-xaml-hosting-api)
+(Xaml Islands). This enables you to use XAML APIs from a Win32 context.
+
+
+#### Adding XAML Hosting code
+
+First and foremost, you'll need to add the following to your test's `precomp.h`:
+
+```c++
+#include <winrt/Windows.system.h>
+#include <winrt/Windows.Foundation.Collections.h>
+#include <winrt/Windows.UI.Xaml.Hosting.h>
+#include <windows.ui.xaml.hosting.desktopwindowxamlsource.h>
+```
+
+If you hit a compile warning that refers to `GetCurrentTime`, you'll probably
+also need the following, after you've `#include`'d `Windows.h`:
+
+```c++
+#ifdef GetCurrentTime
+#undef GetCurrentTime
+#endif
+```
+
+Then, somewhere in your test code, you'll need to start up Xaml Islands. I've done this in my `TEST_CLASS_SETUP`, so that I only create it once, and re-use it for each method.
+
+```c++
+
+class TabTests
+{
+    TEST_CLASS_SETUP(ClassSetup)
+    {
+        winrt::init_apartment(winrt::apartment_type::single_threaded);
+        // Initialize the Xaml Hosting Manager
+        _manager = winrt::Windows::UI::Xaml::Hosting::WindowsXamlManager::InitializeForCurrentThread();
+        _source = winrt::Windows::UI::Xaml::Hosting::DesktopWindowXamlSource{};
+
+        return true;
+    }
+
+private:
+    winrt::Windows::UI::Xaml::Hosting::WindowsXamlManager _manager{ nullptr };
+    winrt::Windows::UI::Xaml::Hosting::DesktopWindowXamlSource _source{ nullptr };
+```
+
+#### Authoring your test's `AppxManifest.xml`
+
+This alone however is not enough to get XAML Islands to work. There was a fairly
+substantial change to the XAML Hosting API around Windows build 18295, so it
+explicitly requires that you have your executable's manifest set
+`maxversiontested` to higher than that version. However, because TAEF's `te.exe`
+is not so manifested, we can't just use our SxS manifest from before to set that
+version. Instead, you'll need to make TAEF run your test binary in a packaged
+content, with our own appxmanifest.
+
+To do this, we'll need to author an `Appxmanifest.xml` to use with the test, and
+associate that manifest with the test.
+
+Here's the AppxManifest we're using:
+
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<Package xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities" xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10" xmlns:uap="http://schemas.microsoft.com/appx/manifest/uap/windows10" IgnorableNamespaces="uap">

+        <ActivatableClass ActivatableClassId="Microsoft.Terminal.Settings.KeyChord" ThreadingModel="both" />
+      </InProcessServer>
+    </Extension>
+    <!-- More extensions here -->
+  </Extensions>
+</Package>
+```
+
+Change the `Identity.Name` and `Properties.DisplayName` to be more appropriate
+for your test, as well as other properties if you feel the need. TAEF will
+deploy the test package and remove it from your machine during testing, so it
+doesn't terribly matter what these values are.
+
+MAKE SURE that `MaxVersionTested` is higher than `10.0.18295.0`. If it isn't,
+XAML islands will still prevent you from activating it.
+
+UNDER NO CIRCUMSTANCE should you change the `<Application Id="TE.ProcessHost"
+Executable="TE.ProcessHost.exe" EntryPoint="Windows.FullTrustApplication">`
+line. This is how TAEF activates the TAEF host for your test binary. You might
+get a warning about `TE.ProcessHost.exe` being deprecated in favor of
+`TE.ProcessHost.UAP.exe`, but I haven't had success with the UAP version.
+
+Lower in the file, you'll see the `Extensions` block. In here you'll put each of
+the winrt dependencies that your test needs, much like we did for the previous
+manifest. Note that the syntax is _not_ exactly the same as the SxS manifest.
+
+#### Copy the AppxManifest to your `$(OutDir)`
+
+Again, we'll need to copy this appxmanifest adjacent to the test binary so we
+can load it from the test. We'll do this similar to how we did the SxS manifest
+before. The complete `PostBuildEvent` now looks like this:
+
+```xml
+  <ItemDefinitionGroup>
+    <PostBuildEvent>
+      <Command>
+        (xcopy /Y &quot;$(SolutionDir)src\cascadia\ut_app\TerminalApp.Unit.Tests.manifest&quot; &quot;$(OutDir)\TerminalApp.Unit.Tests.manifest*&quot; )
+
+        (xcopy /Y &quot;$(SolutionDir)src\cascadia\ut_app\TerminalApp.Unit.Tests.AppxManifest.xml&quot; &quot;$(OutDir)\TerminalApp.Unit.Tests.AppxManifest.xml*&quot; )
+
+        (xcopy /Y &quot;$(SolutionDir)$(Platform)\$(Configuration)\TerminalConnection\TerminalConnection.dll&quot; &quot;$(OutDir)\TerminalConnection.dll*&quot; )
+        (xcopy /Y &quot;$(SolutionDir)$(Platform)\$(Configuration)\TerminalSettings\TerminalSettings.dll&quot; &quot;$(OutDir)\TerminalSettings.dll*&quot; )
+        (xcopy /Y &quot;$(SolutionDir)$(Platform)\$(Configuration)\TerminalControl\TerminalControl.dll&quot; &quot;$(OutDir)\TerminalControl.dll*&quot; )
+      </Command>
+    </PostBuildEvent>
+  </ItemDefinitionGroup>
+```
+
+The new line here is the line referencing
+`TerminalApp.Unit.Tests.AppxManifest.xml`. You can only have one
+`PostBuildEvent` per project, so don't go re-defining it for each additional
+step - MsBuild will only use the last one. Again, this is probably not the best
+way of copying these files over, but it works.
+
+#### Use the AppxManifest in the test code
+
+Now that we have the AppxManifest being binplaced next to our test, we can
+finally reference it in the test. Instead of using the `ActivationContext` from
+before, we'll use two new properties to tell TAEF to run this test as a package,
+and to use our manifest as the AppxManifest for the package.
+
+```c++
+    BEGIN_TEST_CLASS(TabTests)
+        TEST_CLASS_PROPERTY(L"RunAs", L"UAP")
+        TEST_CLASS_PROPERTY(L"UAP:AppXManifest", L"TerminalApp.Unit.Tests.AppxManifest.xml")
+    END_TEST_CLASS()
+```
+
+The complete Xaml Hosting test now looks like this:
+
+```c++
+    class TabTests
+    {
+        BEGIN_TEST_CLASS(TabTests)
+            TEST_CLASS_PROPERTY(L"RunAs", L"UAP")
+            TEST_CLASS_PROPERTY(L"UAP:AppXManifest", L"TerminalApp.Unit.Tests.AppxManifest.xml")
+        END_TEST_CLASS()
+
+        TEST_METHOD(TryCreateXamlObjects);
+
+        TEST_CLASS_SETUP(ClassSetup)
+        {
+            winrt::init_apartment(winrt::apartment_type::single_threaded);
+            // Initialize the Xaml Hosting Manager
+            _manager = winrt::Windows::UI::Xaml::Hosting::WindowsXamlManager::InitializeForCurrentThread();
+            _source = winrt::Windows::UI::Xaml::Hosting::DesktopWindowXamlSource{};
+
+            return true;
+        }
+
+    private:
+        winrt::Windows::UI::Xaml::Hosting::WindowsXamlManager _manager{ nullptr };
+        winrt::Windows::UI::Xaml::Hosting::DesktopWindowXamlSource _source{ nullptr };
+    };
+    void TabTests::TryCreateXamlObjects(){ ... }
+```
+
+Congratulations, you can now use XAML types from your unittest.
+
+### Using types from `Microsoft.UI.Xaml`
+
+Let's say you're extra crazy and you're using the `Microsoft.UI.Xaml` nuget
+package. If you've followed all the steps above exactly, you're probably already
+fine! You've already put the types in your appxmanifest (there are a lot of
+them). You should be able to call the `Microsoft.UI.Xaml` types without any
+problems.
+
+This is because of a few key lines we already put in the appxmanifest:
+
+```xml
+  <Dependencies>
+    <TargetDeviceFamily Name="Windows.Universal" MinVersion="10.0.18362.0" MaxVersionTested="10.0.18362.0" />
+    <PackageDependency Name="Microsoft.VCLibs.140.00.Debug" MinVersion="14.0.27023.1" Publisher="CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US" />
+    <PackageDependency Name="Microsoft.VCLibs.140.00.Debug.UWPDesktop" MinVersion="14.0.27027.1" Publisher="CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US" />
+  </Dependencies>
+```
+
+Without these `PackageDependency` entries for the VCLibs, Microsoft.UI.Xaml.dll
+will not be able to load.

+# Terminal Contributor's Guide
+
+Below is our guidance for how to report issues, propose new features, and submit contributions via Pull Requests (PRs).
+
+## Open Development Workflow
+
+The Windows Terminal team is VERY active in this GitHub Repo. In fact, we live in it all day long and carry out all our development in the open!
+
+When the team finds issues we file them in the repo. When we propose new ideas or think-up new features, we file new feature requests. When we work on fixes or features, we create branches and work on those improvements. And when PRs are reviewed, we review in public - including all the good, the bad, and the ugly parts.
+
+The point of doing all this work in public is to ensure that we are holding ourselves to a high degree of transparency, and so that the community sees that we apply the same processes and hold ourselves to the same quality-bar as we do to community-submitted issues and PRs. We also want to make sure that we expose our team culture and "tribal knowledge" that is inherent in any closely-knit team, which often contains considerable value to those new to the project who are trying to figure out "why the heck does this thing look/work like this???"
+
+### Repo Bot
+
+The team triages new issues several times a week. During triage, the team uses labels to categorize, manage, and drive the project workflow.
+
+We employ [a bot engine](https://github.com/microsoft/terminal/blob/master/doc/bot.md) to help us automate common processes within our workflow.
+
+We drive the bot by tagging issues with specific labels which cause the bot engine to close issues, merge branches, etc. This bot engine helps us keep the repo clean by automating the process of notifying appropriate parties if/when information/follow-up is needed, and closing stale issues/PRs after reminders have remained unanswered for several days.
+
+Therefore, if you do file issues, or create PRs, please keep an eye on your GitHub notifications. If you do not respond to requests for information, your issues/PRs may be closed automatically.
+
+---
+
+## Before you start, file an issue
+
+Please follow this simple rule to help us eliminate any unnecessary wasted effort & frustration, and ensure an efficient and effective use of everyone's time - yours, ours, and other community members':
+
+> 👉 If you have a question, think you've discovered an issue, would like to propose a new feature, etc., then find/file an issue **BEFORE** starting work to fix/implement it.
+
+### Search existing issues first
+
+Before filing a new issue, search existing open and closed issues first: This project is moving fast! It is likely someone else has found the problem you're seeing, and someone may be working on or have already contributed a fix!
+
+If no existing item describes your issue/feature, great - please file a new issue:
+
+### File a new Issue
+
+* Don't know whether you're reporting an issue or requesting a feature? File an issue
+* Have a question that you don't see answered in docs, videos, etc.? File an issue
+* Want to know if we're planning on building a particular feature? File an issue
+* Got a great idea for a new feature? File an issue/request/idea
+* Don't understand how to do something? File an issue/Community Guidance Request
+* Found an existing issue that describes yours? Great - upvote and add additional commentary / info / repro-steps / etc.
+
+When you hit "New Issue", select the type of issue closest to what you want to report/ask/request:
+![New issue types](/doc/images/new-issue-template.png)
+
+### Complete the template
+
+**Complete the information requested in the issue template, providing as much information as possible**. The more information you provide, the more likely your issue/ask will be understood and implemented. Helpful information includes:
+
+* What device you're running (inc. CPU type, memory, disk, etc.)
+* What build of Windows your device is running
+
+  👉 Tip: Run the following in PowerShell Core
+
+  ```powershell
+  C:\> $PSVersionTable.OS
+  Microsoft Windows 10.0.18909
+  ```
+
+  ... or in Windows PowerShell
+
+  ```powershell
+  C:\> $PSVersionTable.BuildVersion
+
+  Major  Minor  Build  Revision
+  -----  -----  -----  --------
+  10     0      18912  1001
+  ```
+
+  ... or Cmd:
+
+  ```cmd
+  C:\> ver
+
+  Microsoft Windows [Version 10.0.18900.1001]
+  ```
+
+* What tools and apps you're using (e.g. VS 2019, VSCode, etc.)
+* Don't assume we're experts in setting up YOUR environment and don't assume we are experts in `<your distro/tool of choice>`. Teach us to help you!
+* **We LOVE detailed repro steps!** What steps do we need to take to reproduce the issue? Assume we love to read repro steps. As much detail as you can stand is probably _barely_ enough detail for us!
+* If you're reporting a particular character/glyph not rendering correctly, the specific Unicode codepoint would be MOST welcome (e.g. U+1F4AF, U+4382)
+* Prefer error message text where possible or screenshots of errors if text cannot be captured
+* We MUCH prefer text command-line script than screenshots of command-line script.
+* **If you intend to implement the fix/feature yourself then say so!** If you do not indicate otherwise we will assume that the issue is our to solve, or may label the issue as `Help-Wanted`.
+
+### DO NOT post "+1" comments
+
+> ⚠ DO NOT post "+1", "me too", or similar comments - they just add noise to an issue.
+
+If you don't have any additional info/context to add but would like to indicate that you're affected by the issue, upvote the original issue by clicking its [+😊] button and hitting 👍 (+1) icon. This way we can actually measure how impactful an issue is.
+

+
+## Contributing fixes / features
+
+For those able & willing to help fix issues and/or implement features ...
+
+### To Spec or not to Spec
+
+Some issues/features may be quick and simple to describe and understand. For such scenarios, once a team member has agreed with your approach, skip ahead to the section headed "Fork, Branch, and Create your PR", below.
+
+Small issues that do not require a spec will be labelled Issue-Bug or Issue-Task.
+
+However, some issues/features will require careful thought & formal design before implementation. For these scenarios, we'll request that a spec is written and the associated issue will be labeled Issue-Feature.
+
+Specs help collaborators discuss different approaches to solve a problem, describe how the feature will behave, how the feature will impact the user, what happens if something goes wrong, etc. Driving towards agreement in a spec, before any code is written, often results in simpler code, and less wasted effort in the long run.
+
+Specs will be managed in a very similar manner as code contributions so please follow the "Fork, Branch and Create your PR" below.
+
+### Writing / Contributing-to a Spec
+
+To write/contribute to a spec: fork, branch and commit via PRs, as you would with any code changes.
+
+Specs are written in markdown, stored under the `\doc\spec` folder and named `[issue id] - [spec description].md`.
+
+👉 **It is important to follow the spec templates and complete the requested information**. The available spec templates will help ensure that specs contain the minimum information & decisions necessary to permit development to begin. In particular, specs require you to confirm that you've already discussed the issue/idea with the team in an issue and that you provide the issue ID for reference.
+
+Team members will be happy to help review specs and guide them to completion.
+
+### Help Wanted
+
+Once the team have approved an issue/spec, development can proceed. If no developers are immediately available, the spec can be parked ready for a developer to get started. Parked specs' issues will be labeled "Help Wanted". To find a list of development opportunities waiting for developer involvement, visit the Issues and filter on [the Help-Wanted label](https://github.com/microsoft/terminal/labels/Help-Wanted).
+
+---
+
+## Development
+
+### Fork, Clone, Branch and Create your PR
+
+Once you've discussed your proposed feature/fix/etc. with a team member, and you've agreed an approach or a spec has been written and approved, it's time to start development:
+
+1. Fork the repo if you haven't already
+1. Clone your fork locally
+1. Create & push a feature branch
+1. Create a [Draft Pull Request (PR)](https://github.blog/2019-02-14-introducing-draft-pull-requests/)
+1. Work on your changes
+
+### Code Review
+
+When you'd like the team to take a look, (even if the work is not yet fully-complete), mark the PR as 'Ready For Review' so that the team can review your work and provide comments, suggestions, and request changes. It may take several cycles, but the end result will be solid, testable, conformant code that is safe for us to merge.
+
+> ⚠ Remember: **changes you make may affect both Windows Terminal and Windows Console and may end up being re-incorporated into Windows itself!** Because of this, we will treat community PR's with the same level of scrutiny and rigor as commits submitted to the official Windows source by team members and partners.
+
+### Merge
+
+Once your code has been reviewed and approved by the requisite number of team members, it will be merged into the master branch. Once merged, your PR will be automatically closed.

+# Azure cloud shell connector
+
+## Abstract
+
+This spec goes over the details of how a feature enabling Windows Terminal users to connect to the Azure cloud shell should behave. It includes implementation and design considerations. 
+
+## Inspiration
+
+The idea is to give developers access to their Azure services smoothly within the Windows Terminal app, letting them engage with Azure technologies in a convenient manner. By integrating the Azure cloud shell into Windows Terminal, we can do just that. 
+
+## Solution Design
+
+The flowchart below shows the process by which the Azure cloud shell will be integrated into Windows Terminal. 
+
+![Sol Design](images/solDesign.png)
+
+The first three steps - authenticating the user, requesting a cloud shell and requesting a terminal - will be done via http requests. These requests will use the [cpprestsdk](https://github.com/Microsoft/cpprestsdk) library as that library is also owned by Microsoft, making it easy to resolve issues should any arise. 
+
+Authenticating the user will use [device code flow](https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/wiki/Device-Code-Flow) since Windows Terminal does not support browser access (yet). As for the authentication endpoint, Azure AD v1.0 will be used because Azure AD v2.0 (also known as Microsoft Identity Platform) [does not support login to personal accounts with device code flow](https://github.com/AzureAD/microsoft-authentication-library-for-dotnet/wiki/Device-Code-Flow#constraints) at this time. Furthermore, upon successful authentication, the login/token information will be stored so that users will not need to repeatedly go through device code flow for future logins. Since this is sensitive information, the tokens will be stored with [Windows Storage](https://docs.microsoft.com/en-us/uwp/api/windows.storage) and encrypted with [Windows Security Data Protection](https://docs.microsoft.com/en-us/uwp/api/windows.security.cryptography.dataprotection.dataprotectionprovider). 
+
+The last step - connecting to the terminal - will be done via a websocket connection to allow easier communication between the app and the server. 
+
+The entire feature will be implemented in an isolated manner - i.e. it should have little to no dependency on the Windows Terminal app itself. This will allow the feature to become a plugin/extension once Windows Terminal supports plugins. More specifically, the connector will ascribe to the existing ITerminalConnection interface, making this simply another type of connection that Windows Terminal can make. 
+
+## UI/UX Design
+
+Upon successful implementation, a new profile option will appear for users as illustrated in the picture below (the profile will have its own unique icon when implemented).

+
+As for the rest of the UI, the implementation will adopt the user's preferences from the Windows Terminal app. 
+
+## Capabilities
+
+### Accessibility
+
+This feature will not impact accessibility of Windows Terminal. 
+
+### Security
+
+Any feature that connects to a network introduces some security risks. However, with proper usage of Azure AD v1.0 and careful storage of tokens received from the server, these risks will be mitigated. 
+
+### Reliability
+
+This feature will not impact reliability of Windows Terminal. 
+
+### Compatibility
+
+With the implementation being mostly decoupled from the Windows Terminal app itself, no existing code/behaviours should break due to this feature. 
+
+### Performance, Power, and Efficiency
+
+This feature will not impact performance, power or efficiency of Windows Terminal.
+
+## Potential Issues
+
+1. This implementation depends on another open source project, [cpprestsdk](https://github.com/Microsoft/cpprestsdk). Thus, any issues with their code will affect this feature. However, given that cpprestsdk is a Microsoft project, we can expect a level of reliability and also solve issues internally if needed.
+2. The proposed authentication endpoint is Azure AD v1.0 instead of Azure AD v2.0 (also known as Microsoft Identity Platform). Azure AD v1.0 is still supported for now, but there is a risk of it becoming deprecated at some point in the future. However, given that it is once again another Microsoft-owned project, we can request support for it through an internal channel. In the worst case, our implementation can switch to Microsoft Identity Platform (which would only requires some minor edits to the http requests). 
+3. The Azure cloud shell API is not public, meaning that implementing this feature in an official capacity would require app permissions from the Azure cloud shell team. This brings about another dependency, but once again issues can be resolved through internal Microsoft channels. 
+
+## Future considerations
+
+This could potentially be the first plugin for Windows Terminal once the app allows for plugins/extensions!

+# Editing Windows Terminal JSON Settings
+
+One way (currently the only way) to configure Windows Terminal is by editing the profiles.json settings file. At
+the time of writing you can open the settings file in your default editor by selecting
+`Settings` from the WT pull down menu.
+
+The settings are stored in the file `$env:LocalAppData\Packages\Microsoft.WindowsTerminal_<randomString>\RoamingState\profiles.json` 
+
+Details of specific settings can be found [here](../cascadia/SettingsSchema.md). A general introduction is provided below.
+
+The settings are grouped under four headings:
+
+1. Global: Settings that apply to the whole application e.g. Default profile, initial size etc.
+2. Key Bindings: Actually a sub field of the global settings, but worth discussing separately
+3. Profiles: A group of settings to be applied to a tab when it is opened using that profile. E.g. shell to use, cursor shape etc.
+4. Schemes: Sets of colors for background, text etc. that can be used by profiles
+
+## Global Settings
+
+These settings define startup defaults.
+
+* Theme
+* Title Bar options
+* Initial size
+* Default profile used when WT is started
+
+Example settings include
+
+```json
+    "defaultProfile" : "{58ad8b0c-3ef8-5f4d-bc6f-13e4c00f2530}",
+    "initialCols" : 120,
+    "initialRows" : 50,
+    "requestedTheme" : "system",
+    "keybinding" : []
+    ...
+```
+
+## Key Bindings
+
+This is an array of key chords and shortcuts to invoke various commands.
+Each command can have more than one key binding.
+
+NOTE: Key bindings is a subfield of the global settings and
+key bindings apply to all profiles in the same manner.
+
+## Profiles
+
+A profile contains the settings applied when a new WT tab is opened. Each profile is identified by a GUID and contains
+a number of other fields.
+
+* Which command to execute on startup - this can include arguments.
+* Starting directory
+* Which color scheme to use (see Schemes below)
+* Font face and size
+* Various settings to control appearance. E.g. Opacity, icon, cursor appearance, display name etc.
+* Other behavioural settings. E.g. Close on exit, snap on input, .....
+
+Example settings include
+
+```json
+    "closeOnExit" : true,
+    "colorScheme" : "Campbell",
+    "commandline" : "wsl.exe -d Debian",
+    "cursorColor" : "#FFFFFF",
+    "cursorShape" : "bar",
+    "fontFace" : "Hack",
+    "fontSize" : 9,
+    "guid" : "{58ad8b0c-3ef8-5f4d-bc6f-13e4c00f2530}",
+    "name" : "Debian",
+    "startingDirectory" : "%USERPROFILE%/wslhome"
+    ....
+```
+
+The profile GUID is used to reference the default profile in the global settings.
+
+The values for background image stretch mode are documented [here](https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.media.stretch)
+
+##  Color Schemes
+
+Each scheme defines the color values to be used for various terminal escape sequences.
+Each schema is identified by the name field. Examples include
+
+```json
+    "name" : "Campbell",
+    "background" : "#0C0C0C",
+    "black" : "#0C0C0C",
+    "blue" : "#0037DA",
+    "foreground" : "#F2F2F2",
+    "green" : "#13A10E",
+    "red" : "#C50F1F",
+    "white" : "#CCCCCC",
+    "yellow" : "#C19C00"
+    ...
+```
+
+The schema name can then be referenced in one or more profiles.
+
+## Configuration Examples:
+
+### Add a custom background to the WSL Debian terminal profile
+
+1. Download the Debian SVG logo https://www.debian.org/logos/openlogo.svg
+2. Put the image in the
+ `$env:LocalAppData\Packages\Microsoft.WindowsTerminal_<randomString>\RoamingState\`
+ directory (same directory as your `profiles.json` file).
+
+    __NOTE__:  You can put the image anywhere you like, the above suggestion happens to be convenient.
+3. Open your WT json properties file.
+4. Under the Debian Linux profile, add the following fields:
+```json
+    "backgroundImage": "ms-appdata:///Roaming/openlogo.jpg",
+    "backgroundImageOpacity": 0.3,
+    "backgroundImageStretchMode":  "Fill",
+```
+5. Make sure that `useAcrylic` is `false`.
+6. Save the file.
+7. Jump over to WT and verify your changes.
+
+Notes:
+1. You will need to experiment with different color settings
+and schemes to make your terminal text visible on top of your image
+2. If you store the image in the UWP directory (the same directory as your profiles.json file),
+then you should use the URI style path name given in the above example.
+More information about UWP URI schemes [here](https://docs.microsoft.com/en-us/windows/uwp/app-resources/uri-schemes).
+3. Instead of using a UWP URI you can use a:
+    1. URL such as
+`http://open.esa.int/files/2017/03/Mayer_and_Bond_craters_seen_by_SMART-1-350x346.jpg` 
+    2. Local file location such as `C:\Users\Public\Pictures\openlogo.jpg`

+# Windows Terminal User Documentation
+
+NOTE: At the time of writing Windows Terminal is still under active development and many things will
+change. If you notice an error in the docs, please raise an issue. Or better yet, please file a PR with an appropriate update!
+
+## Installing Windows Terminal 
+
+### From Source Code
+
+Follow the instructions in this repo's [README](/README.md#developer-guidance).
+
+### From the Microsoft Store
+
+1. Make sure you have upgraded to the current Windows 10 release (at least 1903)
+2. Search for Windows Terminal in the Store
+3. Review the minimum system settings to ensure you can successfully install Windows Terminal
+4. Install in the normal fashion
+
+## Starting Windows Terminal
+
+From the Windows Start menu, select Windows Terminal and run the application.
+
+Note: You can right click on the application item and run with Windows Administrator privilege if required.
+
+The default shell is PowerShell.
+
+
+### Command line options
+
+None at this time. See issue [#607](https://github.com/microsoft/terminal/issues/607)
+
+## Multiple Tabs
+
+Additional shells can be started by hitting the `+` button from the tab bar -- a new instance of the
+default shell is displayed (default shortcut `Ctrl+Shift+1`).
+
+## Running a Different Shell
+
+Note: The following text assumes you have WSL installed.
+
+To choose a different shell (e.g. `cmd.exe` or WSL `bash`) then
+
+1. Select the `down` button next to the `+` in the tab bar
+2. Choose your new shell from the list (more on how to extend the list in the config section)
+
+## Starting a new PowerShell tab with admin privilege
+
+There is no current plan to support this feature for security reaons. See issue [#623](https://github.com/microsoft/terminal/issues/632)
+
+## Using cut and paste in the Terminal window
+
+### With PowerShell
+
+* Copy - Select the text with mouse (default left button), then right click with mouse
+* Paste - by default use `<ctrl>+v`>, or right click with mouse
+
+### With Bash
+
+* Copy - Select the text with mouse (default left button), then right click with mouse
+* Paste - Right click with mouse
+
+## Add a "Open Windows Terminal Here" to File Explorer
+
+Not currently supported "out of the box". See issue [#1060](https://github.com/microsoft/terminal/issues/1060)
+
+## Configuring Windows Terminal
+
+At the time of writing all Windows Terminal settings are managed via a json file.
+
+From the `down` button in the top bar select Settings (default shortcut `Ctrl+,`).
+
+Your default json editor will open up the Terminal settings file. The file can be found
+at `$env:LocalAppData\Packages\Microsoft.WindowsTerminal_<randomString>/RoamingState`
+
+An introduction to the the various settings can be found [here](UsingJsonSettings.md).
+
+The list of valid settings can be found in the [Profiles.json Documentation](../cascadia/SettingsSchema.md) doc.
+
+## Tips and Tricks:
+
+1. In PowerShell you can discover if the Windows Terminal is being used by checking for the existence of the environment variable `WT_SESSION`.
+
+    Under pwsh you can also use
+`(Get-Process -Id $pid).Parent.Parent.ProcessName -eq 'WindowsTerminal'`
+
+    (ref https://twitter.com/r_keith_hill/status/1142871145852440576)
+
+2. Terminal zoom can be changed by holding `Ctrl` and scrolling with mouse.
+3. If `useAcrylic` is enabled in profiles.json, background opacity can be changed by holding `Ctrl+Shift` and scrolling with mouse.
+4. Please add more Tips and Tricks

+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and

+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in

+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material, You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:

+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);

+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database, provided You do not Share
+     Adapted Material;
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.
