Here are the most useful resources I've found this week:
0. The Documentation
Silverlight alpha documentation and samples - very thorough for "alpha" bits!
1. Silverlight Mind Map
This is a "mind map" of Silverlight online resources complete with hyperlinks.
2. Jamie Cool and Nick Kramer Presentation
These are videos of the two-part presentation by Jamie Cool and Nick Kramer at MIX07, called Building Silverlight Applications Using .NET (Part 1 of 2) and Building Silverlight Applications Using .NET (Part 2 of 2). The two comprise a really instructive discussion of building managed code apps in the Silverlight 1.1 alpha.
You might also be interested in the other MIX07 presentations available online.
3. Scott Guthrie Silverlight Summary and Videos
After his keynote demo at MIX07, Scott Guthrie published a summary of the Silverlight Keynote and announcements in his blog, complete with a 22-minute video of him building a Silverlight application from scratch.
The blog entry is a thorough summary of an amazing keynote, and it's great to have the video as well. Thanks to Scott for for taking the time after the keynote to put this resource together.
(aside: Just in case you missed it, here's Robert Scoble's interview with Scott Guthrie from shortly after the keynote. You can tell Scott was still buzzing 🙂 )
Upcoming Silverlight Podcast with Brad Abrams:
Just for good measure, here's a photo of Tom Raftery and Sean Foley jammin' it Guitar Hero style at MIX07.
And now that this blog entry has gone completely off piste, it's time for me to stop.
