+
+## Project Scope
+
+The Electron.NET project ultimately tries to provide a framework for developing cross-platform client applications on the basis of .NET and Electron. Anything that is related to this goal will be considered. The project aims to be as close to Electron with .NET as a basis as possible. If your contribution does not reflect that goal, the chances of accepting it are limited.
+
+## Code License
+
+This is an open source project falling under the [MIT License](../LICENSE). By using, distributing, or contributing to this project, you accept and agree that all code within the Electron.NET project and its libraries are licensed under MIT license.
+
+## Becoming a Contributor
+
+Usually appointing someone as a contributor follows this process:
+
+1. An individual contributes actively via discussions (reporting bugs, giving feedback to existing or opening new issues) and / or pull requests
+2. The individual is either directly asked, invited or asks for contributor rights on the project
+3. The individual uses the contribution rights to sustain or increase the active contributions
+
+Every contributor might have to sign the contributor's license agreement (CLA) to establish a legal trust between the project and its contributors.
+
+## Working on Electron.NET
+
+### Issue Discussion
+
+Discussion of issues should be placed transparently in the issue tracker here on GitHub.
+
+* [General issues, bugs, new features](https://github.com/ElectronNET/Electron.NET/issues)
+* [General discussions, help, exchange of ideas](https://github.com/ElectronNET/Electron.NET/discussions)
+
+### Modifying the code
+
+Electron.NET and its libraries uses features from the latest versions of C# (e.g., C# 10). You will therefore need a C# compiler that is up for the job.
+
+1. Fork and clone the repo.
+2. First try to build the ElectronNET.Core library and see if you get the tests running.
+3. You will be required to resolve some dependencies via NuGet.
+
+The build system of Electron.NET uses NUKE.
+
+### Code Conventions
+
+Most parts in the Electron.NET project are fairly straight forward. Among these are:
+
+* Always use statement blocks for control statements, e.g., in a for-loop, if-condition, ...
+* You may use a simple (throw) statement in case of enforcing contracts on argument
+* Be explicit about modifiers (some files follow an older convention of the code base, but we settled on the explicit style)
+
+### Development Workflow
+
+1. If no issue already exists for the work you'll be doing, create one to document the problem(s) being solved and self-assign.
+2. Otherwise please let us know that you are working on the problem. Regular status updates (e.g. "still in progress", "no time anymore", "practically done", "pull request issued") are highly welcome.
+3. Create a new branch—please don't work in the `main` branch directly. It is reserved for releases. We recommend naming the branch to match the issue being addressed (`feature/#777` or `issue-777`).
+4. Add failing tests for the change you want to make. Tests are crucial and should be taken from W3C (or other specification).
+5. Fix stuff. Always go from edge case to edge case.
+6. All tests should pass now. Also your new implementation should not break existing tests.
+7. Update the documentation to reflect any changes. (or document such changes in the original issue)
+8. Push to your fork or push your issue-specific branch to the main repository, then submit a pull request against `develop`.
+
+Just to illustrate the git workflow for Electron.NET a little bit more we've added the following graphs.
+
+Initially, Electron.NET starts at the `main` branch. This branch should contain the latest stable (or released) version.
+
+Here we now created a new branch called `develop`. This is the development branch.
+
+Now active work is supposed to be done. Therefore a new branch should be created. Let's create one:
+
+```sh
+git checkout -b feature/#777
+```
+
+There may be many of these feature branches. Most of them are also pushed to the server for discussion or synchronization.
+
+```sh
+git push -u origin feature/#777
+```
+
+Now feature branches may be closed when they are done. Here we simply merge with the feature branch(es). For instance the following command takes the `feature/#777` branch from the server and merges it with the `develop` branch.
+
+```sh
+git checkout develop
+git pull
+git pull origin feature/#777
+git push
+```
+
+Finally, we may have all the features that are needed to release a new version of Electron.NET. Here we tag the release. For instance for the 1.0 release we use `v1.0`.
+
+```sh
+git checkout main
+git merge develop
+git tag v1.0
+```
+
+(The last part is automatically performed by our CI system. Don't tag manually.)
+
+### Versioning
+
+The rules of [semver](http://semver.org/) don't necessarily apply here, but we will try to stay quite close to them.
+
+Prior to version 1.0.0 we use the following scheme:
+
+1. MINOR versions for reaching a feature milestone potentially combined with dramatic API changes
+2. PATCH versions for refinements (e.g. performance improvements, bug fixes)
+
+After releasing version 1.0.0 the scheme changes to become:
+
+1. MAJOR versions at maintainers' discretion following significant changes to the codebase (e.g., API changes)
+2. MINOR versions for backwards-compatible enhancements (e.g., performance improvements)
+3. PATCH versions for backwards-compatible bug fixes (e.g., spec compliance bugs, support issues)
+
+#### Code style
+
+Regarding code style like indentation and whitespace, **follow the conventions you see used in the source already.** In general most of the [C# coding guidelines from Microsoft](https://msdn.microsoft.com/en-us/library/ff926074.aspx) are followed. This project prefers type inference with `var` to explicitly stating (redundant) information.
+
+It is also important to keep a certain `async`-flow and to always use `ConfigureAwait(false)` in conjunction with an `await` expression.
+
+## Backwards Compatibility
+
+We always try to remain backwards compatible beyond the currently supported versions of .NET.
+
+For instance, in December 2025 there have been activity to remove .NET 6 support from the codebase. We rejected this. Key points:
+
+1. We have absolutely no need to drop `.net6` support. It doesn't hurt us in any way.
+2. Many are still using `.net6`, including Electron.NET (non-Core) users. It doesn't make sense to force them to update two things at the same time (.NET + Electron.NET).
+3. We MUST NOT and NEVER update `Microsoft.Build.Utilities.Core`. This will make Electron.NET stop working on older Visual Studio and MSBuild versions. There's are also no reasons to update it in the first place.
+
+It's important to note that the Microsoft label of "Out of support" on .NET has almost no practical meaning. We've rarely (if ever) seen any bugs fixed in the same .NET version which mattered. The bugs that all new .NET versions have are much worse than mature .NET versions which are declared as "out of support". Keep in mind that the LTS matters most for active development / ongoing supported projects. If, e.g., a TV has been released a decade ago it most likely won't be patched. Still, you might want to deploy applications to it, which then naturally would involve being based on "out of support" versions of the framework.
+
+TL;DR: Unless there is a technical reason (e.g., a crucial new API not being available) we should not drop "out of support" .NET versions. At the time of writing (December 2025) the minimum supported .NET version remains at `.net6`.
+
+## Timeline
+
+**All of this information is related to ElectronNET.Core pre-v1!**
+
+We pretty much release whenever we have something new (i.e., do fixes such as a 0.1.1, or add new features, such as a 0.2.0) quite quickly.
+
+We will go for a 1.0.0 release of this as early as ~mid of January 2026 (unless we find some critical things or want to extend the beta phase for ElectronNET.Core). This should be sufficient time to get some user input and have enough experience to call it stable.

+# Migration Checks
+
+Electron.NET includes automatic build-time validation checks that help users migrating from previous versions avoid common configuration issues. These checks run automatically during the build process and provide helpful guidance when problems are detected.
+
+## Overview
+
+When you build an Electron.NET project, the following validation checks are performed:
+
+| Code | Check | Description |
+|------|-------|-------------|
+| [ELECTRON001](#1-packagejson-not-allowed) | package.json not allowed | Ensures no package.json exists outside ElectronHostHook |
+| [ELECTRON002](#2-electron-manifestjson-not-allowed) | electron-manifest.json not allowed | Detects deprecated manifest files |
+| [ELECTRON003](#3-electron-builderjson-location) | electron-builder.json location | Verifies electron-builder.json exists in Properties folder |
+| [ELECTRON004](#3-electron-builderjson-location) | electron-builder.json wrong location | Warns if electron-builder.json is found in incorrect locations |
+| [ELECTRON005](#4-parent-paths-not-allowed-in-electron-builderjson) | Parent paths not allowed | Checks for `..` references in config |
+| [ELECTRON006](#5-publish-profile-validation) | ASP.NET publish profile mismatch | Warns when ASP.NET projects have console-style profiles |
+| [ELECTRON007](#5-publish-profile-validation) | Console publish profile mismatch | Warns when console projects have ASP.NET-style profiles |
+
+---
+
+## 1. package.json not allowed
+
+**Warning Code:** `ELECTRON001`
+
+### What is checked
+
+The build system scans for `package.json` and `package-lock.json` files in your project directory. These files should not exist in the project root or subdirectories (with one exception).
+
+### Why this matters
+
+In previous versions of Electron.NET, a `package.json` file was required in the project. The new version generates this file automatically from MSBuild properties defined in your `.csproj` file.
+
+### Exception
+
+A `package.json` file **is allowed** in the `ElectronHostHook` folder if you're using custom host hooks. This is the only valid location for a manually maintained package.json.
+
+### How to fix
+
+1. **Open your project's `.csproj` file**
+2. **Add the required properties** to a PropertyGroup with the label `ElectronNetCommon`:
+
+```xml
+<PropertyGroup Label="ElectronNetCommon">
+  <ElectronPackageId>my-electron-app</ElectronPackageId>
+  <Title>My Electron App</Title>
+  <Version>1.0.0</Version>
+  <Description>My awesome Electron.NET application</Description>
+  <Company>My Company</Company>
+  <Copyright>Copyright © 2025</Copyright>
+  <ElectronVersion>30.0.9</ElectronVersion>
+</PropertyGroup>
+```
+
+3. **Delete the old `package.json`** file from your project root
+
+> **See also:** [Migration Guide](Migration-Guide.md) for complete migration instructions.
+
+---
+
+## 2. electron-manifest.json not allowed
+
+**Warning Code:** `ELECTRON002`
+
+### What is checked
+
+The build system checks for the presence of `electron.manifest.json` or `electron-manifest.json` files in your project.
+
+### Why this matters
+
+The `electron.manifest.json` file format is deprecated. All configuration should now be specified using:
+- MSBuild properties in your `.csproj` file (for application metadata)
+- The `electron-builder.json` file in the `Properties` folder (for build configuration)
+
+### How to fix
+
+1. **Migrate application properties** to your `.csproj` file (see [Migration Guide](Migration-Guide.md))
+2. **Move the `build` section** from `electron.manifest.json` to `Properties/electron-builder.json`
+3. **Delete the old `electron.manifest.json`** file
+
+**Example electron-builder.json:**
+```json
+{
+    "compression": "maximum",
+    "win": {
+        "icon": "Assets/app.ico",
+        "target": ["nsis", "portable"]
+    },
+    "linux": {
+        "icon": "Assets/app.png",
+        "target": ["AppImage", "deb"]
+    },
+    "mac": {
+        "icon": "Assets/app.icns",
+        "target": ["dmg", "zip"]
+    }
+}
+```
+
+---
+
+## 3. electron-builder.json Location
+
+**Warning Codes:** `ELECTRON003`, `ELECTRON004`
+
+### What is checked
+
+- `ELECTRON003`: Verifies that an `electron-builder.json` file exists in the `Properties` folder
+- `ELECTRON004`: Warns if `electron-builder.json` is found in incorrect locations
+
+### Why this matters
+
+The `electron-builder.json` file must be located in the `Properties` folder so it can be properly copied to the output directory during publishing.
+
+### How to fix
+
+1. **Create the Properties folder** if it doesn't exist
+2. **Move or create** `electron-builder.json` in `Properties/electron-builder.json`
+3. **Remove** any `electron-builder.json` files from other locations
+
+**Expected structure:**
+```
+MyProject/
+├── Properties/
+│   ├── electron-builder.json    ✅ Correct location
+│   ├── launchSettings.json
+│   └── PublishProfiles/
+├── MyProject.csproj
+└── Program.cs
+```
+
+---
+
+## 4. Parent paths not allowed in electron-builder.json
+
+**Warning Code:** `ELECTRON005`
+
+### What is checked
+
+The build system scans the `electron-builder.json` file for parent-path references (`..`).
+
+### Why this matters
+
+During the publish process, the `electron-builder.json` file is copied to the build output directory. Any relative paths in this file are resolved from that location, not from your project directory. Parent-path references (`../`) will not work correctly because they would point outside the published application.
+
+### How to fix
+
+1. **Move resource files** (icons, installers, etc.) inside your project folder structure
+2. **Configure the files** to be copied to the output directory in your `.csproj`:
+
+```xml
+<ItemGroup>
+  <Content Include="Assets\**\*">
+    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
+  </Content>
+</ItemGroup>
+```
+
+3. **Update paths** in `electron-builder.json` to use relative paths without `..`:
+
+**Before (incorrect):**
+```json
+{
+    "win": {
+        "icon": "../SharedAssets/app.ico"
+    }
+}
+```
+
+**After (correct):**
+```json
+{
+    "win": {
+        "icon": "Assets/app.ico"
+    }
+}
+```
+
+---
+
+## 5. Publish Profile Validation
+
+**Warning Codes:** `ELECTRON006`, `ELECTRON007`
+
+### What is checked
+
+The build system examines `.pubxml` files in the `Properties/PublishProfiles` folder and validates that they match the project type:
+
+- **ELECTRON006**: For **ASP.NET projects** (using `Microsoft.NET.Sdk.Web`), checks that publish profiles include `WebPublishMethod`. This property is required for proper ASP.NET publishing.
+
+- **ELECTRON007**: For **console/other projects** (not using the Web SDK), checks that publish profiles do NOT include the `WebPublishMethod`  property. These ASP.NET-specific properties are incorrect for non-web applications.
+
+### Why this matters
+
+Electron.NET supports both ASP.NET and console application project types, each requiring different publish profile configurations:
+
+| Project Type | SDK | Expected Properties |
+|--------------|-----|---------------------|
+| ASP.NET (Razor Pages, MVC, Blazor) | `Microsoft.NET.Sdk.Web` | `WebPublishMethod`, no `PublishProtocol` |
+| Console Application | `Microsoft.NET.Sdk` | `PublishProtocol`, no `WebPublishMethod` |
+
+Using the wrong publish profile type can lead to incomplete or broken builds.
+
+### How to fix
+
+1. **Delete existing publish profiles** from `Properties/PublishProfiles/`
+2. **Create new publish profiles** using the Visual Studio Publishing Wizard:
+   - Right-click on the project in Solution Explorer
+   - Select **Publish...**
+   - Follow the wizard to create a **Folder** publish profile
+
+For correct publish profile examples for both ASP.NET and Console applications, see **[Package Building](../Using/Package-Building.md#step-1-create-publish-profiles)**.
+

+
+## Disabling Migration Checks
+
+If you need to disable specific migration checks (not recommended), you can set the following properties in your `.csproj` file:
+
+```xml
+<PropertyGroup>
+  <!-- Disable all migration checks -->
+  <ElectronSkipMigrationChecks>true</ElectronSkipMigrationChecks>
+</PropertyGroup>
+```
+
+> ⚠️ **Warning:** Disabling migration checks may result in build or runtime errors. Only disable checks if you fully understand the implications.

+# Using custom_main.js
+
+This guide explains how to include and use a `custom_main.js` file in your Electron.NET application for advanced Electron/Node.js customization.
+
+## Why use custom_main.js?
+
+- Register custom protocol handlers (e.g., `myapp://`) — protocols must be registered before the app is fully initialized
+- Integrate Node.js modules (e.g., telemetry, OS APIs)
+- Control startup logic (abort, environment checks)
+- Set up IPC messaging or preload scripts
+
+## Step-by-Step Process
+
+### 1. Create the custom_main.js file
+
+Place your custom logic in `electron/custom_main.js`:
+
+```javascript
+module.exports.onStartup = function(host) {
+    // Example: Register a global shortcut for opening dev tools
+    const { app, globalShortcut, BrowserWindow } = require('electron');
+    app.on('ready', () => {
+        const ret = globalShortcut.register('Control+Shift+I', () => {
+            BrowserWindow.getAllWindows().forEach(win => win.webContents.openDevTools());
+            console.log('Ctrl+Shift+I is pressed: DevTools opened!');
+        });
+    });
+    app.on('will-quit', () => {
+        globalShortcut.unregisterAll();
+    });
+    return true;
+};
+```
+
+### 2. Configure your .csproj to copy custom_main.js to output
+
+Add this to your `.csproj` file:
+
+```xml
+<ItemGroup>
+  <None Update="electron\custom_main.js">
+    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
+    <TargetPath>.electron\custom_main.js</TargetPath>
+  </None>
+</ItemGroup>
+```
+
+### 3. Build and run your app
+
+Use the standard build/run commands:
+
+```powershell
+dotnet build
+dotnet run
+```
+
+Electron.NET will automatically load and execute your `custom_main.js` before initializing the .NET backend.
+
+## Advanced Usage
+
+Use environment variables to control features:
+
+  ```javascript
+  const env = process.env.ASPNETCORE_ENVIRONMENT || 'Production';
+  if (env === 'Development') { /* enable dev features */ }
+  ```
+
+## Notes
+
+- `custom_main.js` must use CommonJS syntax (`module.exports.onStartup = ...`).
+- Place the file in your source directory and copy it to `.electron` using `.csproj`.
+- Electron.NET will abort startup if `onStartup` returns `false`.
