Last fall I visited 0redev in Sweden and gave a “What’s New in Silverlight 3” talk. THey’ve just released the video if you interested in wathcing it:
Shawn Wildermuth - What’s New in Silverlight 3 from Øredev on Vimeo.
Now that Silverlight 3 is available, learning all the new features can be a chore. In this talk I will walk through all the new features and show you the most compelling pieces from both Silverlight 3 and Blend 3.
