Yesterday, we posted an update to the Windows Phone 7 Training Kit and updated all the bits to work with the April Refresh of the Windows Phone 7 Tools and Visual Studio 2010 (RTM). This kit includes some great content to get a jump-start on building apps targeted for Windows Phone 7.

The kit includes the videos from all the Windows Phone breakout sessions at MIX’10, as well as hands-on labs covering Windows Phone Fundamentals, Silverlight for Windows Phone and XNA Framework 4.0 for Windows Phone.

There is a new lab in this rev of the kit on Using Push Notifications. This particular lab walks through a scenario of a Weather application that receives updates through the Push Notification service even in times when the app isn’t running. Push Notifications is an important piece in the Windows Phone development paradigm as it gives applications the ability to receive process notifications in the background. I’d highly recommend going through this lab as Push Notifications is an area that most Windows Phone developers will need to get a good handle on.

Enjoy!
