Unpackaged scenarios with WinAppSDK broken

[j0shuams]

Using a C#/WinRT component with WinUI 3 types from unpackaged apps has some issues. In the C++ case, a runtime error is thrown "No package identity". In the C# case, a WinAPPSDK error is thrown "No match for key in index"

To Reproduce

1. Follow the steps here to make an unpackaged app
2. Create a C#/WinRT component
3. Add a project reference in the C++ app to the C# component

Expected behavior*
App runs normally

Version Info
Windows APP SDK - 1.1.0-20220215.0-CI-experimental
VS2022
net6.0-windows10.0.19041

We may be holding it wrong, the docs are not entirely correct. Track these issues for this work:

• Unpackaged winappsdk app needs supportedOS  MicrosoftDocs/windows-dev-docs#3691
• "Building unpackaged app" tutorial should explain how to get XAML to work in unpackaged MicrosoftDocs/windows-dev-docs#3695

@j0shuams should this be closed? Seems like a doc issue, not a cswinrt issue.
