Windows Phone 7 is brand new, totally fresh operating system that will appear in phones before Christmas. The new platform is a complete rewrite and offers lots of interesting opportunities to third party developers. The development platform for Windows Phone 7 is all based around managed code and the tools and frameworks you already know and love. This presentation you will give you an overview of the Windows Phone 7 development platform, and how you can leverage your existing Silverlight skills to build great applications for the Windows Phone 7 marketplace. The session assumes some prior knowledge of Silverlight, as the focus of this presentation will be features that are specific to the phone. It will not only cover the basics of the Windows Phone 7 platform, but also how you can re–use many of the same patterns, frameworks, techniques and practices that you use when building regular Silverlight applications.
