Live Tiles are all the new rage and talk of the world in WP7 and with Windows 8 release just around the corner they are going to become even more important to your software. Your users are going to come to expect your live tile to actually be alive and meaningful. To do a Live Tile correctly however takes planning and an understanding of the Metro Experience Live Tile update architecture and life cycle. I'm hoping to help you to make sure your Live Tile is Great and plays well with Metro. In this session you will discover what makes for a good Live Tile, a bad Live Tile, and a "just don't do that". We'll walk thru: determining what should be on a Live Tile (and what shouldn't); How to make the tile engaging and informative without being distracting; Creating a Web Service that feeds the Live Tile in the way that best works with the Metro UI life cycle. Audience Participation will be greatly appreciated! Many of the Live Tile examples that are currently out there that show you "how" to do Live Tiles are not Best Practice! We look thru some not so good examples and really understand WHY they are should be avoided. For Live Tiles to be useful to the End Users we must use our great power with great responsibility.
