Easiest way to make .NET DLL visible to COM?

Question

I have a proprietary .NET DLL which I would like to use in a COM client.

Currently when I use regasm it says: warning RA0000 : No types were registered

Since I don't have the source code I can't set the classes to ComVisible or whatever else is required.

How can I easily make this DLL visible to COM?

You are expecting a software vendor to recompile DLLs for me at my request? — CJ7, Jan 23 '13 at 02:10
No, I'd expect a software vendor to give you quote for the required work. This is the way the world works. — Hans Passant, Jan 23 '13 at 02:14

You need to write a "COM callable wrapper". Here are a few links:

Some of these are quite old, but I imagine the principles have remained the same.

Edit: someone seems to have written a generic wrapper:
