Numerous Exceptions While Attaching Debugger

[Mike-E-angelo]

Current behavior

I am using a very basic and simple SLN:
https://github.com/unoplatform/Uno.Samples/blob/master/reference/Counter/XAML-MVVM/Counter-XAML-MVVM.sln

While pressing F5 to launch the application into an Android emulator, I am finding that it works as expected 1 out of 10 times. Most of the time the emulator sits there waiting to be attached:

But other times there are errors:

 warning: Could not connect Jdwp. System.Exception: Process Not Found.

And:

Also, it takes nearly 100 seconds from pressing F5 to seeing the very basic application load in the Android emulator. This seems like a really long time.

Expected behavior

Pressing F5 quickly launches the application without error.

Thank you for your efforts out there. :)🙏

Thanks for the report. Those issues are coming from Visual Studio, it would be best for your to open an issue directly here: https://developercommunity.visualstudio.com/VisualStudio.

Are you able to reproduce the same behavior using vscode?

I appreciate your patience here @jeromelaban as I learn all the moving pieces. I was indeed also encountering this with Maui and this appears to be Visual Studio-related. Taking this off your plate. I appreciate all your efforts and impressive accomplishments out there. 🙏
