In the VS2005 beta and ctp releases the default behavior was that new projects weren’t saved when you created the project. This enabled you to easily create a simple web app or any other VS2005 project, do some testing and discard the files. That way your project folder didn’t get filled up with “Project 1”, “Project 2” and so fourth. Before this functionality came along in VS2005 you would typically use SnippetCompiler to do this kind of “testing”. 

In the final release of VS2005 this isn’t the default behavior, and I’ve been asked a couple of times if Microsoft removed this feature. No, they didn’t. If you go to the Tools – Options – Project and Solutions settings, and uncheck “Save new projects when created” you get this behavior back.
