ResourceDictionary Controls trigger runtime error with embedded CanvasControl from Microsoft.Graphics.Win2D

[StevoSM]

Describe the bug

Adding Microsoft.Graphics.Win2D to a Project and embedding a CanvasControl in a Window or even UserControl works great. However, when embedding a CanvasControl in a ResourceDictionary control, it results in a runtime error, which isn't consistent.

The attached solution demonstrates the issue. It is configured to show a CanvasControl in all 3 scenarios.

@StevoSM I see the related discussion was closed and you were able to get around your issue. Do you still need support on this bug, or we are good to close.

@hiteshkrmsft Because of other issues with Templated Controls, we had to abandon them for the time being and switch to User Controls. Whichever path one desires, I would think it should be possible to include and use Win2D to help render content. While this approach works with User Controls no problem, you get a crash deep in WinUI when trying this with Templated Controls. The attached project demonstrates the crash - simply build and run. Since we had to switch to User Controls, we are not triggering any issues, however, I would expect others to try to use Win2D with Templated Controls and expect it to work, so I would expect you would want to fix this crash if possible.
