SortingItemsWinUI3Demo Exception and Strange Windowing Behavior

eleanorleffler opened this issue · 0 comments

Describe the bug

When running on Version 1809 / Debug x64, SortingItemsWinUI3Demo throws an exception - see screenshot below. In addition to the exception, I will get strange windowing behavior afterwards when I try to view/maximize any windows I currently have open, they will not appear or maximize. To alleviate this, I have been forced to lock/log out/restart my computer.

Steps to reproduce the bug

  1. Open the SortingItemsWinUI3Demo in Visual Studio 2019.
  2. Update the Targeting versions appropriately to match system's.
    In my case, I updated them to:
    Target version: Windows 10, version 1809 (10.0; Build 17763)
    Min version: Windows 10, version 1803 (10.0; Build 17134)
  3. Build and run with Debug x64.
