The deep dive session was held last friday, with Praveen Srivasta doing 2 sessions on Vista for developers and Office for developers , and i did a session on WF (Workflow Foundation).
My session on WF went ok, but i ran out of time and had to skip the demos on State Machine Workflows and XOML only authoring mode. I am very interested in Workflow technologies and i do feel WF is a technology that is as important and cool as WPF and WCF. If anyone have any questions or comments do post here or in the .NET forum.
