Unless you use a special setting in Visual Studio, windowed executables start with the WinMain function, not the regular main function. So you should either be creating a console app, be using WinMain or use the setting to use the regular main function.
If you include the Windows headers, then the linker expects you to provide a WinMain function, not the regular main. The WinMain entry point provides Windows-specific data like HINSTANCEs.
