Repeatedly building and deploying causes deployment errors due to file being held by another process error.

See original GitHub issue

Repeatedly building and running a winui desktop C# app ends up with a build failure sometimes. You can recover by restarting visual studio. Also, I notice that sometimes rebuilding and F5 from visual studio does not terminate the app instance that is already running.

Here is the error message when it fails.

Issues relating to Visual Studio should be filed through VS itself: https://learn.microsoft.com/en-us/visualstudio/ide/how-to-report-a-problem-with-visual-studio?view=vs-2022.
