If this is purely native C++ (not C++/CLI), you can use only the method with P/Invoke. Please see:
http://en.wikipedia.org/wiki/P/invoke[^],
http://msdn.microsoft.com/library/en-us/vcmxspec/html/vcmg_PlatformInvocationServices.asp[^].

This CodeProject article can also be useful:
Essential P/Invoke[^].

Sometimes you need much tighter integration. In this case, another approach could be beneficial: using C++/CLI and mixed-mode (managed + unmanages) project. Such project can use everything in C++ resources, as much as regular C++ could use, and all CLI types and members to the project, some of them wrapping unmanaged code. This way, you can create a class library using native C++, but used as a regular .NET assembly. You can reference this assembly as any other .NET assembly in your C# projects. Please see:
http://en.wikipedia.org/wiki/C%2B%2B/CLI[^],
