Silverlight for Windows Phone 7 Development Series (3): Multimedia development

Objective

This article describes how to create a new Silverlight for Windows Phone application in the previous article, which describes how to develop multimedia applications on Windows Phone. Also describes the media file formats supported by the current beta version of Windows Phone, as well as some of the limitations and points of attention for Windows Phone Multimedia development.
