C# app with C++ DLL

[Oleg]

Hi ,

How can I use classes implemented in C++ (unmanaged and
packed in DLL) by C# application ?

I'm not talking about DLL function invocation that passes
primitives but about entire class usage (data and
functions).

Thanks a lot !

P.S. The DLL must stay unmanages since it's used by other
application.

The easiest way is probably to write a wrapper in Managed C++ for it.

As I told earlier the DLL must remain unmanaged since
it's used by other application....
or managed and unmanaged C++ classes can reside in the
same DLL ?

Right, but the MC++ wrapper can be compiled to a separate DLL.

C# app -> MC++ DLL -> Native C++ DLL

Yes
