eek! As a follow up to my previous post, just wanted to share with you a cool hands on lab put on by our Swiss MSDN team. It is a Line of Business (LOB) type application and is built for Beta 1. Given the new controls and features of Silverlight 2 Beta2, updating the lab could be a great exercise to build Silverlight strength :)
