Error : MFC requires use of Winsock2.h after migrating Visual C++ project to Visual Studio 2013

Question

After migrating a project from Visual C++ to Visual Studio 2013 I receive the following error on building the project:

C1189:#error: MFC requires use of Winsock2.h

In stdafx.h I've included the following headers:

#include <afxwin.h> 
#include <afxext.h>
#include <afxdtctl.h>
#include <afxcmn.h>
#include <afxsock.h>
#include <WinSock2.h>

I've tried to change the order of the include files ( winsock before and after MFC headers ) but still the same errors.

Can anyone give me some ideas to solve this issues ? Thank you !

Read the error message again, doesn't it say "winsock**2**.h"? — Some programmer dude, Jan 12 '16 at 09:36

@JoachimPileborg I've forgot to specify: I've included `winsock2.h` instead of `winsock` but I still have the same errors. — Madalin, Jan 12 '16 at 09:41
1. Edit the question to show rather than . 2. Have you tried a "rebuild all " after changing stdafx.h? 3. Have you checked that nothing else is including ? — Martin Bonner supports Monica, Jan 12 '16 at 09:42
1. Done 2. Yes. I've tried rebuild all 3. Yes, I've checked and nothing else is including — Madalin, Jan 12 '16 at 09:44

Solved ! One of the .cpp files from Extern dependencies was including <winsock.h>. I've removed the include line and the problem was solved. Thank you !
