Yes

How are you calling your DLL?

If it is purely native C++, you will have to expose C functions and call them via P/Invoke. Is this what you're doing?

Consuming Unmanaged DLL Functions

The other possibilites involve COM (convert you DLL into a in-process COM server and use the .NET-COM interop mechanism) and C++/CLI (create a C++/CLI DLL which implements a .NET API to expose you native C++ functionality)
