As you know for sure, the tiles can be attached or detached from the home screen and some particular software can take advantage of double size tiles. While this is not a feature available to developers, in OS7.5, the tiles gained new features and a new set of APIs that you can use to enrich your applications. As an example you are now able to update your tiles from inside the application and you can use double faced tiles to improve information to the user. In this article I would like to explore these new features and show how to take advantage of them, while porting your software to the new operating system.
Andrea Boschin's article has enough examples and clear text to get you started on making the most of the Live Tile experience while you are coding, and it's good to see more articles and help out there for developers coming to the platform.
