Why do I get So Many Errors?

So I opened up some of The Template Projects Like The Shooter Game and all The Code has Errors In It do you know how to fix this ? Thanks In advance also Im using Visual Studio 2013 Express

Hey WeDaBest-

The errors in the screenshot are IntelliSense trying to predict what it thinks is needed which is not always necessary. If you’ve not made any changes to the code you should still be able to compile it.
