Well, Microsoft things usually only works well with other Microsoft things only, and unreliable to outside techs (wcf, activeX). Better not use them if you aim for interoperability and stick to simple techs, even if you need to declare more classes that way.

I share the same idea, since I've found typescript (express) is usually enough for backend rest. But I cannot refute that C# is more reliable with it's variables than ts. Can't say much about Java though.
