Yesterday I gave a presentation on VSTO at the third annual Portland Code Camp. I demonstrated an Outlook 2007 add-in that used Outlook Form Regions, WCF, and WPF to integrate Amazon.com Wish Lists with contact items. As my first public speaking event since joining Microsoft last November, I thought it went pretty well.
I've attached the add-in that I created during the presentation. You will need to sign up with Amazon and receive an access key before it can be run. The add-in was developed with Visual Studio "Orcas" Beta1.
