C# and C++ are NOT ABI compatible like C++ and Delphi, so you cannot export virtual class members (methods) and declare them purely virtual on the calling side an invoke them, because C# cannot handle vtbl's of C++ objects. I would suggest you to wrap your C++ classes by COM, so you have another positive side effect, that other COM compatible languages can use your classes too.
