When starting a project, in the new project wizard, select
General on the left pane, and select
Empty Project on the right side. Create your project.
This should make a completely empty project so that you can focus on learning the language, rather then MSVC++ adding its own stdafx file (Which isnt needed, anyways.)
---
If you want to stick with using stdafx, you need to add this to your source file:
#include "stdafx.h"
