You can't just use a COM control from .NET - a wrapper, or Runtime Callable Wrapper (RCW), has to be created first. This wrapper is in an COM interop assembly. You use tlbimp.exe to create a COM interop assembly and reference that assembly in your project. If you don't, you have to resort to many excrutiatingly painful methods of redefining interfaces and creating instances of COM objects at runtime and you don't get any marshaling or Type safety for free. You definitley DO NOT want to do it this way, and it's recommended that you don't.

For more information on creating interop assemblies, please read Exposing COM Components to the .NET Framework[^].
