So now that LINQPad has enabled intellisense SQL Server Management Studio, Query Analyzer, and even Joseph Albahari's (LINQPad creator) own QueryEx have all been zapped from my memory.  I'll no longer flounder in antiquated ANSI SQL, but instead flourish in fully typed C#/LINQ code.... [More]

With a couple of extension methods, you can do exactly that: preview the SQL before it executes.... [More]
