How to build a plugin for Pidgin?

Question

C++ / C#

Good day, gentlemen. It is impossible to assemble a working plugin for Pidgin in any way. Haven't even started coding yet. I just take the ready-made sources, compile to dll, put it in the pidgin / plugins folder, but it is not in the list of modules.
I need a dll for Windows (of course), I compile in Ubuntu. Took an example where there were source codes and the collected dll. If the assembled one is already placed in the plugins folder, then it is displayed in Pidgin in the modules. If you collect and put it yourself - it is not displayed.
Can someone give or write a simple source code (which would say hello world somewhere) and show how to compile it correctly?

How it is?
Do you expect GCC compiled into Linux formats to work under MinGW?
