Ok, I have an update, when trying this on an earlier version of Visual Studio (17.4.8) the issue is no longer happening.

This then appears to be a Uno Platform / Visual Studio 17.6.3 (also tried .2) issue as MAUI does not have this issue either

This seems like a Visual Studio bug.

People are complaining in https://stackoverflow.com/questions/76337441/xamarin-forms-breakpoint-not-hit-on-android-no-compatible-code-running-on-the-t in 17.6 as well and not related to Uno Platform.

I can't find any vsfeedback item for this though.

Xamarin forms breakpoint not hit on android [No compatible code running on the thread]

When I put a breakpoint on an event function on any project, even on a project I just created. I get: No compatible code running on the thread This happens only on Android projects, on Uwp projects...

Thanks @Youssef1313. Yeah I got the opinion of it being Uno related only because it doesn't happen with MAUI. Seeing that stack overflow link it does appear to be maybe more of an issue with Visual Studio and Xamarin platforms (including Uno Platform).

I'm actually surprised this issue hasn't become more public considering how blocking it can be.

This bug is now stopping my team as well. Flying blind without the ability to debug...

Hey, so the only way I was able to get around this was to roll back visual studio to 17.4.8. hopefully this gets fixed soon. This issue doesn't happen with MAUI but does affect Xamarin/Uno projects
