There already exists C# for Android, it recently became free too when Microsoft bought up Xamarin (the company formerly maintain Mono and the Xamarin Android and iOS wrappers). Microsoft is really pushing .NET Core and the open .NET platform, really an awesome move for developers.

What the parent wanted was official support from Google for Xamarin's Android API wrapper or a complete rewrite of core parts of the OS in .NET instead of Java. It seems fairly unlikely because of all the effort Google has invested in their Java VM and JIT/AOT compilers, but maybe that'll change.

I agree with most of it. But I personally think .net/C# simply to not bring enough advances over Java to even think of changing core parts. Most advantages that get mentioned are app developer conveniences.
