Interestingly, the Rust windows crate is generated from an MSIL assembly. And same metadata might be used to generate C# bindings thanks to cswin32 [1] project. The meta-assembly generation (Win32 metadata project) is based on clangsharp and it's fairly straightforward to generate interop code for native Windows libraries. Some time ago I described this process on my blog for the detours library [2]
