Call C# from C++(unmanaged)

Can I call C# code from unmanaged C++ code? If yes, how?

I saw the same question posted in this newsgroup last year but there was no
useful answer there, so posting it again hoping someone might have tried it
by now and knows the answer.

Thanks

Ok, I found the following article on MSDN. It explains using managed code
from unmanaged code and vice versa. But the code to be used has to be a COM
component. If anyone knows any solution that does not require the managed
classes to be converted to COM component, please let me know.

Hmmm, the only thing I can think of is for you to host the runtime in
your process...

might be a good place to start :)

Jyoti,

If you have C++ code with you then you can compile same C++ (Legacy)code
under VS .NET compiler with /Clr switch
Look for documentation here from MSDN :
http://msdn.microsoft.com/library/de...ompilation.asp

I tried achieve same goal last year and some of the steps I have documented
in my blog http://harishds.weblogs.us/archives/2004_04.html
