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.
