If you use the Web Express version of Visual Studio 2012, you will notice one thing missing; creating a console application. The solution is fairly simple. I found a blog post at Possibly the most boring blog ever that explains it perfectly. So instead of rehashing what has already been posted, I will let you use that link above.
In a nutshell though, you will create a new class library. In its property page set its output type to Console Application. Please see the original post for screen shots and more details.
