Can't include Winsock2.h in MSVC 2010

Question

I cannot include WinSock2.h in a msvc++2010 project. At first I though it was something I was doing wrong, so I created an empty project to test my sanity. The empty project

Answer 1

I made sure that an #include "Winsock2.h" is before any #include "windows.h" and "#include "Winsock.h" and this solved the case.

Just a matter of patience, look at includes one by one and establish this order, first #include "Winsock2.h" then #include "windows.h"

I checked the recursive includes, I spotted the header files which include (recursively) some #include "windows.h" and "#include "Winsock.h"and write a#include "Winsock2.h". in this files, i added#include "Winsock2.h"` as the first include.
