IIS Express works differently and is recommended for development. You may have to change a property in the web project to get it to run with IIS Express. When using IIS Express, when you hit F5 to run your site, it starts up IIS Express. Your project will be assigned an unused port number.

>I don't know, but it looks like I have no IIS at all. So, I went to Windows Features and installing version 7.5 now.
