Description

Description

Xamarin.Forms took a dependency on Win2D.uwp at v3.6. However Win2D does not support ARM64, so that support was lost in that move.

Steps to Reproduce

  1. Build a 3.6 UWP app for ARM64
  2. Deploy and run on an ARM64 device

Expected Behavior

App runs

Actual Behavior

App will crash

Research direction
Investigate the dependency on Win2D.uwp introduced in Xamarin.Forms 3.6. Check the related issue #5188 for discussion. Look for alternative libraries that support ARM64 or consider making Win2D optional. The fix may require changes to package dependencies in the Xamarin.Forms solution.
