Two ways:
managed C++/CLI wrapper (typesafe, debuggable, etc).
P/Invoke
You can break P/Invoke down into asynchronous messages delivered to a window
procedure via PostMessage (solves cross-thread callback problems) or
synchronous callback to a .NET delegate which is automatically compiled to a
native function pointer by the marshaller.

thanks.
