Joe Albahari's LINQPad and LINQPad Challenge

JoeA's LINQPad is an indispensible tool for LINQ development.

Write a query expression and view the results, the generated SQL, and the extension method / lambda equivalent. Works for both C# and VB!

Joe also dares developers to take the LINQPAd challenge:

1. Locate the shortcut for SQL Management Studio on your Start Menu and move it some place else.
2. In its place, insert a shortcut to LINQPad.
3. For the next week, perform all your ad-hoc SQL queries using only LINQPad.

Teachers say language immersion is highly effective when learning a new language. I'm sure the LINQPad challenge is a worthwhile endeavor to learn the subtleties of LINQ.
