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 listed, are available to watch here and be downloaded in video and audio formats.
