I found another repository that includes an MSVC project file. That's the ZIP-file I sent you. (Unfortunately I cannot find the link to it any longer.)
Looks like I didn't receive it. Could you try to send it again? Thx.

I see again that my programming capabilities are very limited. Why does the compiler make a difference of the result? I mean the program is written in C and I expect every C compiler to produce the same output. I once compiled LyX using MSVC and parallel also MinGW (via cygwin) and the result was the same - a fully functional LyX.
You have to tell the compiler which functions need to be exported in the DLL so they can be called from external programs. There are also different calling conventions. See for example: http://www.willus.com/mingw/yongweiwu_stdcall.html
If the functions are not exported correctly the DLL will compile but the function cannot be called from LyX so it won't link.
