I first discovered LinqPad in a session at Codestock a couple of years ago. Since that time I have used it on almost a daily basis for one thing or another. It is a great place to try out short sections of code, run queries or create snippets that will be reused. I keep a library of useful scripts to help with data management and data retrieval. It also helps keep my reliance on intellisense in check. (I love intellisense, but I think it makes some people dumb) If any of this sounds interesting check out the application. http://www.linqpad.net/
