Summary

  • Self-contained WASDK 2.4.0 ships CoreMessagingXP 10.0.27200.1048, which fail-fasts with 0xC0000602 at the first Window() on Windows 11 25H2 (26200).
  • Switch WindowsAppSDKSelfContained to false so the app uses the installed Microsoft.WindowsAppRuntime.2 2.4.0 package.
  • Drop unused WinUI 2 CommunityToolkit.WinUI 7.1.2.
  • Give the tray icon a generated R glyph so ForceCreate has an IconSource.

Test plan

  • dotnet build Reentry.slnx -c Debug -p:Platform=x64
  • Reentry.exe stays alive and shows the first-run consent window on FUNCULAR-WKS-02 (25H2)
