There were questions about WSAStartup can not find. What to do?

Question

C++ / C#

I am writing a chat on the instructions of the teacher (something like a lab.). There was a problem with WSAStartup.
Did a check and he constantly comes there. This library is missing, how to include it or fix the error?
The code:

WSADATA wsaDate; 
    WORD DLLVersion = MAKEWORD(2, 1); 

    if(WSAStartup(DLLVersion, &wsaDate) != 0); 
    {
        std::cout << "Error" << std::endl;
        exit(1);
    }

Linked Libraries:

#pragma comment(lib, "ws2_32.lib")
#include <winsock2.h> 
#include <iostream> 
#include <conio.h>

Thank you in advance.
