WPF Hands on lab - building an Outlook clone

One of the questions I get asked most when talking about Windows Presentation Foundation is around whether this technology is just for 'whizz bang fancy pants graphics stuff' (I'm paraphrasing) and not really for serious business type apps.

The answer I hope is obvious - it's BOTH. And now there is a Hands-On-Lab which you can follow along at home with to create the most serious business type application of all - Outlook (clone).
