C++ Wrapper

Project Description:
I have some code written in C# that does pipe I/O. I have these routines running fine from a C# and a Java program, but now I want to call them from a proprietary language called MQL4 used in trading on the Foreign Exchange. MQL4 is similar looking to C# but does not have asynchronous capabilities, which is how the C# routines work. I made a .dll out of it but discovered that because C# created "managed code" it cannot be called from MQL4.

I evidently need a C++ wrapper to place my C# code in to make it callable from MQL4. A guy I found on Elance developed the C# code, but he has disappeared so I need someone else who is fluent in this stuff to do it.

I am expecting this to be a small piece of code within which my routines will be placed and made into a .dll, callable from the MQL4 program. I might also need a little help getting the routines to work properly from MQL4.
