Come out to Interface Technical Training tomorrow (July 7, 2011) in Phoenix to see me struggle through explaining how to use Jeremy Likness' Sterling No SQL database in your Silverlight applications.
As always, pizza and greet-up starts at 6PM, followed at 6:30 or whenever everybody rounds up by the meeting which runs until 8PM.
If you're anywhere in the area, come on down... I use Sterling all day in an enterprise app, so hopefully I can explain it to you :)
Note: this talk will NOT be WP7-centric, however Sterling is available for WP7 also and the techniques are similar.
