I've got a small C++/CLR project here: https://github.com/roy-t/SuperCompressedDotNet where I've made a small wrapper around BasisU, definitely not production ready but it runs and has some tests. I've also verified the code actually works since it decodes a few textures in my game engine.

Could be useful for inspiration.

I think BasisU also has a C API for the transcoder, which might be more natural to use directly from C#. I haven't investigated that yet.
