Im a .NET Developer, I want to develop a android app with c# ,
i need long term supported language framework to work on,
because Xamarin will end soon ,
Please advice
I tried to create a project in visual studio , i found a android app but its not Xamarin and not MAUI
I think they are mostly 2 options that are offered to you. Either on MAUI as you mentioned. It is the successor of Xamarin therefore will have a long term support.
Or you can opt for Unity https://unity.com/solutions/mobile/android-game-development if your application is more of a game
