Original Pull Request: https://github.com/microsoft/terminal/pull/14637

State: closed
Merged: Yes

This uses shell:AppsFolder to launch elevated instances of the app via
ShellExecuteEx and runas in elevate-shim.exe. The app to launch is
discovered via the GetCurrentApplicationUserModelId API.

e.g. shell:AppsFolder\WindowsTerminalDev_8wekyb3d8bbwe!App

This will fallback to launching WindowsTerminal.exe if it fails to
discover the app user model id to launch.

This also fixes a bug in elevate-shim where the first argument of
WinMain was lost (e.g. new-tab).

Curiously, AppLogic::RunAsUwp() is never called and
AppLogic::IsUwp() is always false when running debug builds locally
(e.g. WindowsTerminalDev). It's not clear if this is an artifact of
development packages or something else.

Validation Steps Performed

Various manual debug/execution scenarios.

Verified the fallback path by running the unbundled app by extracting
the CascadiaPackage_0.0.1.0_x64.msix from the 'drop' build artifact.

Fixes #14501
