Do you think in LINQ?

If not you should download LINQPad from Joseph Albahari’s (of C#3 in a nutshell fame).  It’s a great tool to practicing LINQ expressions and has syntax highlighting (but unfortunatly no intellisense).  Alternatively if you really miss the old Query Analyzer from SQL 2000 days, then Query Express is a good option – super fast 100k stand-alone executable!
