AsyncLock is causing ANR in .NET MAUI with .NET 8

[dharamhbtik]

We were using Nito library with our Xamarin Forms App with .Net Standard 2.1 and was working fine.

Same code base with minimal changes in the C# classes we migrated to .NET MAUI with .NET 8 and we are observing that all the locks are not working properly and app is getting ANR.

Is this library is fully compatible with .NET 8 or .NET 9 ? or there is any adjustments we have to make in order to make it working as per the requirement?

Yes, this library is fully compatible with net 8.0 and 9.0. it does not support trimming or AoT (yet), but it shouldn't cause ANRs on its own. Of course, if an app called a blocking lock method from the UI thread, that could cause an ANR.

Can you post a minimal repro?

it does not support trimming or AoT

Can I still use this library in a packaged WinUI 3 app intended for publication in the Microsoft Store? The app was migrated from UWP, and the implications of not supporting trimming or AoT are unclear.

[StephenCleary]

Neither trimming nor AoT is required for WinUI apps in the Windows Store. I believe the only platform that requires AoT is iPhone, and I'm not even 100% sure it's required there.
