C# <-> Rust is pretty straightforward. Just follow the C FFI side on Rust and C# has standard marshal mechanisms for calling C code.

extern/dllimport[1] Covers most of it. There's automatic conversion for CString/string and delegates as function pointers. If you need to go deeper than that there's the marshal namespace[2]. Going through C++/CX sounds really painful.

Not for someone that knows C++ since C++ARM. :)

I am pretty comfortable with C# and native interop, my issue was trying to map Rust strings with .NET UTF-16 ones, including passing ownership from Rust to .NET side.

If I remember right you can specify encoding as an attribute on the extern decl.
