One of the most popular pages in the Windows Phone 7 documentation is the Code Samples topic. On this page you can find a series of code samples that demonstrate various features of Windows Phone 7. But somewhat hidden away at the bottom of the topic are links to some Starter Kits. These Starter Kits are fully functional applications – in fact, you can find these apps in the Marketplace and try them out on your phone. The complete source code for the entire application is available to download and tinker with. For each Starter Kit, there is a topic in the documentation that highlights some of the more interesting sections of code in the app. Also, Sean McKenna did a couple of presentations on these applications on Channel 9. You can find them at http://channel9.msdn.com/Blogs/LauraFoy/Windows-Phone-7-Apps--Tools and http://channel9.msdn.com/Blogs/LauraFoy/Accelerometer-Helper
