Very simple problem.

I have a solution with 3 projects :

Project A is a plain C++ DLL project
Project B is a managed C++ wrapper DLL for project A (it has A as a Reference)
Project C is a C# project usign the managed C++ wrapper (it has B as a
Reference)

Thus, project C depends indirectly from A, but the dependency checker of
VS.NET seems to overlook that because A is a plain C++ DLL.

The result is that project A's DLL is not copied into the output directory
of project C, preventing project C to run properly.  If I copy the DLL
manually it works.

Is this a bug of VS.NET ?  Is there something I can do to make this work ?  

Thanks,
