Different project types

In the initial release of Visual Web Developer 2008 Express there was one project type: the Web Site Project. The commercial versions of Visual Studio has the second project type — the Web Application Project. In August 2008, Microsoft released Service Pack 1 for Visual Web Developer 2008, which gave users of the free Express edition access to the Web Application Project template as well. This addition is still present in VWD 2010 so you have two options to choose from Web Site Projects and Web Application Project
