I presented this session both in Amsterdam and in Zürich, though I managed to lose my notes in Zürich and had do to a number of the demo's by the seat of my pants which was a bit of a challenge. 

In any event, it was based on a session by Omar Khan of the VWD team that he presented at MIX07, called "Using Visual Studio Codename Orcas to Design And Devloper Rich AJAX Enable Web Sites"
