COM DLL - using Mono instead of MS .NET Framework

I have a DLL written in C# which is acessed by a native EXE (written in Delphi开发者_C百科) via COM. Now I was asked to make it work with Mono (on Windows, not Linux) instead of Microsoft .NET Framework.

Is it possible to be done? If it is, how can I do it?

Possibly, yes.

Mono has had COM-callable wrappers for a while. Check: http://www.mono-project.com/COM_Interop.

Probably the easiest thing to do is to download SharpDevelop and try to compile your existing code for Mono.
