Accessing a C++ object from a C# object

I want to write a C++ Class. I want to be able to access this class from a C# project. What's the easiest way to set up the C++ class to have it the most easily accessible from the C# object?

It depends if you can use managed C++ code or not. Why you need C++ class?

Because I need it to work as a go between with some other C++ Classes and functions. As long as I can use stuff like malloc, free, etc. it should be ok. Its code to work with pointers and other data types not available to C# (USHORT, LPSTR, etc.). Unfortunately, I can't rewrite that portion of the code, so I need to write something that will be able to deal with all that, but be accessible from C#.

Specifically, the code deals with pointers to images. It uses third party code that cannot be re-written, therefore, it has to be in C++. However, the application that's going to use it is in C#.

There's no way to use the "Add Reference..." menu? When I try to add the *.manifest file, it just says it can't add it and to make sure its a valid assembly or COM-component. Is there anyway to just make it a COM-component?

I think no.

If you have an access to C++ code, you can create an wrapper but better way is to write a wrapper in managed c++ code.

Have you thought about the possibility of making a C++ wrapper (as an assembly which uses the pinvoke to call the old legacy code) and reference the assembly from C# ?
