How to call managed C++ dll methods from unmanaged MFC application?

Hi Experts!

I am planning to dedvelop a new component (dll) for my application using managed C++ code and call this component’s methods from my old MFC application. I found a lot of examples how to call unmanaged code from managed, by not opposite way. I am wondering if it is possible to and how it could be done.

Thank you for help,
Olga

In this 2 parts we covered calling DLL libraries from .NET code.
What about:
* Call COM servers
* Call managed components from unmanaged code.

This is exactly what I was looking for, thank you. Is it possible to estimate
the overhead of mono_runtime_invoke() compared to a normal function call?
