Want to learn LINQ? looking for a lightweigh and fast application to evaluate your linq expression? now check this out. i found a very good free application which lets you interactively query SQL databases in a modern query language: LINQ. LINQPad is also a great way to learn LINQ: it comes preloaded with 200 examples from the book, C# 3.0 in a Nutshell.  And finally LINQPad is more than just a LINQ tool: it's a code snippet IDE that instantly executes any C#/VB.net expression, statement block or program. Put an end to those hundreds of Visual Studio Console projects cluttering your source folder! you can get it from here.
