Errors in Visual Studio 2019 when im trying to make a dll file

Question

I would like to create a dll hack for a game and just selected dynamic link library and already have 3 errors.

This is the original code:

// dllmain.cpp : Defines the entry point for the DLL application.
#include "pch.h"

BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    switch (ul_reason_for_call)
    {
    case DLL_PROCESS_ATTACH:
    case DLL_THREAD_ATTACH:
    case DLL_THREAD_DETACH:
    case DLL_PROCESS_DETACH:
        break;
    }
    return TRUE;
}

Errors:

cannot open source file "windows.h" ;
expected a ';' ;
identifier "BOOL" is undefined
