From SilverlightCream.com:

WP7 Contrib – the last messenger: XamlNinja has a great post up extending Laurent's IMessenger to deal with a tricky issue of trying to fire a message from one VM to another even if the 2nd VM isn't alive yet... oh, and this is in WP7Contrib, so go grab it!
Getting an invalid cross-thread exception in Silverlight?: Kevin Dockx has a solution to a problem we've all had... the 'invalid cross-thread exception' ... and the solution is even for those of us trying to do this in a VM... cool and easy solution, Kevin!
Mastering Storyboards One Mistake at a Time: Steve Wortham is back with a tutorial with a great title :) ... check out the progression from one success to another in this picture/title viewer ... don't miss the very end where he has the control rolled up into a CaptionedImageHyperlink, and a link to download it!
Windows Phone 7 - Part #2: Your First Application: Andrea Boschin has part 2 of his SilverlightShow WP7 series up. Lots of good intro material here on the manifest file and app.xaml ... he even gets into the ApplicationBar, phone orientation, and the Metro theme.
How many files are too many files for isolated storage?: Mick Norman alerted me to his blog early this morning, and this is his latest post... interesting tests of how many files are too many for ISO on your WP7... and I have to admit... he's stuffing a boatload of them out there in these tests! ... great info Mick! and thanks for the links.
A Navigator Control For Visiblox Time Series Charts: Colin Eberhardt's latest post is about creating an interactive navigator for large time series datasets in Visiblox charts.... check the images at the top of the post, and it'll be obvious :) ... very cool stuff.
MVVM Frameworks with WP7 support: Rudi Grobler has been very busy and if you check the dates, these posts are all in a day or two! This first highlights two contenders for MVVM on WP7: Caliburn and MVVMLight... both well-supported... quick intro to each followed by good links out to the author's sites
Reading barcodes from your WP7 device: Rudi Grobler also has a cool post up on reading barcodes with your WP7... he's using the ZXing Barcode Scanning Library, and makes quick work of the job.
Taking Sterling for a Test-Drive: Rudi Grobler has a quick intro to Sterlink, Jeremy Likness' ISO database for Silverlight up... quickly taking care of writing and reading back data.
SQLite on WP7: After his discussion of Sterling, Rudi Grobler is now demonstrating the use of SQLite that has been ported to WP7. Check out his demo code... looks pretty easy to use.
Hacking the WP7 Camera (The basics): Rudi Grobler's latest post is on getting direct access to the camera on WP7... be sure to do all the downloads and check out the external links he has.
