P/Invoke a purely C++ library?

Question

Is it possible to P/Invoke a pure C++ library, or does it have to be wrapped in C?

Answer 1

A "pure" C++ library will have its name mangled by the compiler, so it will be hard to get the P/Invoke declaration correct. And a C method gets an underscore at the beginning, which may not be there in C++. And a C++ method needs a this instance as a first parameter, you'd have to give it yourself.

I think that you need to wrap your C++ API in a C-compatible series of methods.
