I have many times had use for the 101 LINQ samples by Microsoft when needing to refresh how to do different kind of queries in with Linq. Often I prefer to have them expressed in Lambda or "fluent" syntax instead of query syntax though, so it has always bothered me that they haven't published them in both formats. Luckily there are tools that allow you to automate conversion between the two formats. I used Resharper by Jetbrains to perform the conversion semi-automatically and have now published all 101*) examples for you in lambda/fluent syntax.
*) Actually there are 102, but hey :)
Head over to linq101.nilzorblog.com to see the result.
