You will need to run regasm.exe with the /tlb command against your .NET assembly and then reference the output type library (tlb) from C++.

I've done this many times before and it can be a pain, especially when you go to deploy it. I recommend using the /codebase switch, which tells the registry where to find your .NET assembly when its classes are instantiated in a COM context. That makes it easy to find in the registry and tweek it as necessary.
