Urgent: Help with calls from C++ DLL to C# DLL using COM

min $50 USD / hour

I have test MFC application that loads MFC Extension DLL. This MFC Extension DLL (C++) must call methods in C# DLL using COM, and C# DLL also calls methods in MFC Extension DLL. This is a proof of concept project and I got it working except one part that makes it unusable. Every time (after the 1st time) that I call C# DLL a new COM object (and C# object) is created instead of getting just the interface of the existing object. Need urgent help today and tomorrow with this. You must have reliable Internet connection so that sharing screen over Skype or TeamViewer works fluently. You also must have good English so I won't guess what you say.
