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. The eight sessions from that event are available to watch here and to be downloaded in video and audio formats. They look like a great start with this exciting new technology.
BTW Clint Rutkas has been blogging about his experiments with Silverlight over at his blog. At his code site (Peace Love Code) he has posted a project that mimics the Microsoft Surface Puzzle application with source code. Should be fun to check out.
