Possible to create a C# DLL with dialogs and GUI -- callable by a C program?

[Harry Whitehouse]

I have a rather large legacy application written in C++. I want to add
some new functionality which would be easier to do in C#.

Is it possible to create a DLL in C# which can be called from my C++
application, with the C# DLL presenting dialogs and other GUI features? I
know I can create a simple non-GUI DLL (e.g. for some computations), but I
haven't seen anything about a dialog laden DLL.

TIA

Yes. This is a very common migration path for existing C++ MFC windows
apps.

See, EG:

Thank you David!

I also found this article.

So it looks like I can pull this off.
