I just released a new article titled about the Validation Application Block (available from http://www.emoreau.com/Entries/Articles/2009/06/The-Validation-Application-Block.aspx).

The Validation Application Block is part of the Microsoft Enterprise Library which is a set of blocks emerging from the Patterns and Practices group. The latest version (version 4.1) was released in October 2008. I personally discovered it recently and cannot live without it anymore.

It was also the topic of my presentation at Montréal CodeCamp held May 30th.
