How do I use a C# dll in C++ COM application?

You have to generate type library for that C# DLL using a command like below

tlbexp MyApp.dll /out:mytypelib.tlb

It will generate tlb file. You can use that tlb file in VC++. You can find tlbexp in .NET Framework direcotry i think.

Hope it helps

Thanks

You can use COM interop for that purpose. See http://msdn2.microsoft.com/en-us/library/zsfww439(VS.80).aspx ("Exposing .NET Framework Components to COM")

My C# dll is a library project.  Most of the functions and properties in it are public and static.  I've been using this in my C# application without creating an instance of this library class.  Is this a qualified candidate for COM interop?  The url seems to be talking about creating an instance of the library class.  Thank you.
