If you thought I was done posting content this week after the video walkthrough, you were wrong :)! I presented on Silverlight at the Indianapolis .NET Developers Association monthly meeting on June 16, 2007. I created a Point Point slide deck (complete with notes) that provides a high-level overview of Silverlight.
In addition, I also provided a walkthrough of creating a media player using Silverlight 1.1 during the meeting.
Feel free to use the content of the slidedeck, I only ask that if you use it, you please post a comment explaining what works and what didn't work with your presentation.
Personally, I feel this is a pretty solid overview especially given the time constraints of the presentation. Enjoy!
