XS is always C, but can call into anything that exposes C-compatible functions in a shared library. So, C works, and C++ works as long as the author of the C++ module exposes plain-old-functions with C calling convention. There are other languages like Rust that can expose C functions from a compiled library even though the library was generated from Rust code. In fact, quite a lot of compiled languages can expose C library APIs just because C is sort of like a common meeting ground for interoperation and language designers want their modules to be widely usable. But XS can't just call into arbitrary other languages on their home turf.

Also I'd hesitate to call C# a compiled language. It's more like a bytecode interpreted language with optional just-in-time compilation. I don't think it can generate .so or .dll files with C calling convention. (but I'm too lazy to go find out)
