C# dll, error 127

I've gone through the forum posts and cannot figure out how to resolve error 127. I created a .def file but I'm not sure why or what to do with it... none of the samples even reference the file, although an earlier post discussed it resolving the issue.

Steps Taken:

1) Placed test2.mqh in experts\include

2) Placed test2.dll in experts\libraries (written in C#)

3) Run test2.mq4 from client terminal

Generates "2008.11.16 22:54:20 Test2 EURUSD,Daily: cannot call function 'SaySomething' from dll 'test2.dll' (error 127)" at runtime.

Hello.

Dont you know you cant call managed code from mql4 directly?

Hello.

Dont you know you cant call managed code from mql4 directly?

You have to write unmanaged (c++ dll) wrapper that calls c# assembly functions.

So, you've got to:

1) Add COM inreface into your assembly.

2) Register this assembly (RegAsm.exe), create type library file .tpl

3) Write c++ wrapper.
