"The Silverlight 1.0 Fire Starter is a one-day event providing developers and designers
information on the concept behind Silverlight as a technology, what tools are useful
in development and the knowledge in order to start building their own applications."
I have seen the "Getting started programming Silverlight" with Jesse Liberty, "Workflow of Silverlight..." with Arturo Toledo and the "Silverlight XAML" with Laurence Moroney. They are all great, especially the first two, and I will recommend all developers, interested in Silverlight, to see these videos.
