title: Stream YouTube videos in a Windows Phone app
body: <p>How do I stream YouTube videos in a Windows Phone app? I've tried using the MediaElement control and setting its Source property with the URL to a video and called the Play() method on the media element, but it didn't work. I want to create a simple video player that plays a video as it is being streamed. What kind of .NET classes do I need to work with?</p>
