When you created the project, you made the wrong choice of application type. When asked whether your project was a console application or a windows application or a DLL or a static library, you made the wrong chose windows application (wrong choice).

Go back, start over again, go to File -> New -> Project -> Win32 Console Application -> name your app -> click next -> click application settings.

For the application type, make sure Console Application is selected (this step is the vital step).

The main for a windows application is called WinMain, for a DLL is called DllMain, for a .NET application is called Main(cli::array<String ^> ^), and a static library doesn't have a main. Only in a console app is main called main

GoTo Project Properties -> Configuration Properties -> Linker -> Advanced

Put "main" to the "Entry Point" field.
