Using C# objects in MFC/C++

[wayne]

How would you use a C# library(DLL) in an MFC application. I created
the following mini library, however after using TlbExp to export the
tlb I don't see how to invoke the Sample to DoSomething. I added the
..Tlb file to my MFC project but the public function is not available.
Does anyone know what I did wrong?

Thanks,
Wayne
