Using C# DLL in Visual Basic 6

I had created a dll in Visual Basic before and  I am calling this dll from my program.

I ran into some problems with the dll as it is fairly complex and it is almost impossible to debug.

If I use C# just to create the dll instead of VB, can anyone tell me how can I call the DLL created in C# from my original VB program? Would there be any effect on performance as the DLL would be created in a non-VB language?

I cant change my original pogram to C#.

Appreciate any help.

Thanks.

You can register the C# assembly with COM Interop (just make sure that it has a strong name) - regasm.exe < your assembly name and path> /tlb. You then reference the type library from VB (or late bind - up to you). Under high-volume concurrency, there is a performance overhead for COM Interop, but for lower volumes it should not be all that significant.
