NativeAOT is not really useable on Android in .NET 9 at all, but it is definitely more useable in .NET 10. I would expect it to remain experimental for at least one more release, though.

Hang in there! I found having a non-coding hobby helps a lot.

Thanks! This is from a long time ago. It likely still works great, .NET for iOS and .NET MAUI still use these ObjC functions today.

I live in Bowling Green, KY on this route where there is an L&N train museum. I can’t imagine how awesome it would be to take a train to Nashville or Louisville instead of lanes and lanes of traffic sadness.
