Depends on what you mean by ecosystem, it hasn't been trapped on Windows for about a decade now. The variety of third party libraries available is quite good, while the standard library is robust enough that you don't need NPM nonsense like LeftPad and IsEven and IsNumber.
Are there particular things about the ecosystem that you worry about (or have heard about)? Biggest complaint I would have is that it seems like many popular open source libraries in the .NET ecosystem decide to go closed source and commercial once they get popular enough.
