Unmanaged C++ to C# interop (replacing CCW)

[EDN Admin]

I want to write a C++/CLI wrapper which will help me in providing interop between unmanaged C++ and C#, basically I want to do the same operation which is done using CCW. My flow would look like this:

Unmanaged C++  --> C++/CLI Wrapper  --> C#  (i.e. the unmanaged c++ client talks to the C# server)

I have searched for this all over the web and in this forum but have not been able to get any definite answer as to how this can be achieved.

I would like to make it clear that I cannot make the unmanaged C++ application CLR compliant, i.e. it cannot be built with /CLR option, because its and existing legacy application.

Any help with references to study materials, suggestions, web links, samples would be helpful.

Thanks in advance.

Kuldeep.
