Using Win2D breaks publishing unpackaged app as single file

[DHancock]

Describe the bug

The application contains a user control that draws itself using composition drawing which requires the Win2D nuget package. When either the debug or release target is published with PublishSingleFile set to true, the previously working application stops with a fail fast exception after opening the main window but before any controls are loaded.

Steps to reproduce the bug

1. Open the solution attached below.
2. Publish the x64 profile using the debug build configuration.
3. Confirm the exe runs ok.
4. Edit the x64 publishing profile setting PublishSingleFile to true.
5. Publish the app again.
6. Run the exe.

Additional context

If I start the published single file using Visual Studio, the output window shows quite a few exception messages. It's difficult to know if these are benign, apart from the last two:

You will find a Microsoft.Graphics.Canvas.dll is suspiciously loitering in the publishing folder. It's the Win2D dll. If I remove all the Win2D code from the repro solution, publish as single file works.

(I'd be surprised if this isn't a known issue)

@codendone FYI

[DHancock]

Retested with current latest packages:

Windows App SDK 1.1.0-preview3
Microsoft.Graphics.Win2D 1.0.3.1

Still fails with same problem.

[appindus-ibiller]

It seems like anything with Win2D refs are breaking if not being deployed to official channels. Still happening with Windows App SDK 1.1.1 stable. We're supposed to be able to make unpackaged apps but despite the November 2021 release being over 6 months ago, official Microsoft packages are still not supporting it. Pretty unreal.
