Telerik have been hosting free webinars covering the Windows Phone 7 platform, and this week (this Thursday to be exact) is based around live tiles. Coverage will also include future improvements included in Mango, so this is well worth the attendance should you be awaiting Mango as a beginner developer.
As well as the above, they have another upcoming webinar on 8th June and it will be covering the Caliburn.Micro framework and how you can utilize it in app development. Both are available to register for and you have the chance in winning a free WP7 device for simply attending! Oh, did we mention that three RadControls for windows Phone 7 licenses per webinar are up for grabs too?
