Hello SWIG,

We've been successfully generating C# bindings to our C API for various .NET/Mono platforms.
However, the recent WinRT platforms introduced changes in .NET core so that many constructs are
no longer supported, e.g., HandleRef  which is at the core if SWIG .NET P/Invoke support.

We wonder if this part of language extension code can be adapted to support WinRT.
For example, replace HandleRef with SafeHandle.

I don't consider myself a .NET expert so please feel free correct me if I'm wrong.

Thanks!
