I read about creating temporary project in Visual Studio some time ago and kind of forgot about it. Few days ago, I needed to create a temp project for trying out something really quick.
There is a setting in Visual Studio that lets you create projects in temp directory and not save all the directory structure in to your main folder structure.
Follow these steps in Visual Studio 2005
Tools -> Options -> Projects and Solutions ->
and uncheck “save new projects when created” check box.
