Using MFC in a "managed C++" application

One of our products is a C++ application - using MFC (MDI). (And we skin the application with Codejock.)

I've been asked if we could "port the application to .NET" - so it would be possible to use, e.g., C# libraries and other .NET features. I know there is something called "C++.NET" - or maybe (if I understand it right) it should be called "managed C++" now. But I don't know much about it.

My question: Is this at all possible? Could we run an MFC-application as "managed C++"? (And can an application using Codejock be run as a "managed C++" application?) There is some other threads about this, but I haven't been able to find "a definitive answer"...

I'd be very grateful for some good advice! :-)

Solution

As far as I understand, you want to keep your MFC/Codejock GUI and allow the use of .NET libraries from you application's C++ code.

This is indeed possible, but for a complete application that is currently compiled as "native" C++ it is probably not such a good idea to convert all of it to being compiled with C++/CLI. "It Just Works (IJW)" is a nice meme, but it doesn't work always :-)

We have the same situation, namely a C++/MFC/Codejock application that needs to call into .NET assemblies. This works mostly without problems:

We have C++/CLI modules that offer a native C++ DLL interface for the native C++ code to call into and that then route these call on to an assembly written in C#.
We also have C++/CLI assemblies that offer a .NET interface for the C# code and then call back into pure native modules.

It should also be possible to have a single (say, exe) project that is compiled natively and you only enable the /clr switch for selected cpp files that need managed interop. And at the end you link everything together. Since we've never mixed it that way, I can't really say anything about this approach however. What I can say for sure though is that it is possible to compile parts on a module as /clr and parts as native.
