Every Live Tile deserves a Windows Phone Application

Over the last week I have been writing about Live Tiles in Windows Phone Mango, how you can create Secondary Live Tiles and how you can display information on the back of Live Tiles and periodically change that information. There is more to write about Live Tiles, but I think it is time to change the topic slightly.

In part 4 of the Live Tile mini series, I introduced an application that adds a Secondary Tile to the Start Screen of your phone. That application is now almost finished in its first version. This free application has a Secondary Tile, it contains an AdControl, deals with location awareness and periodically updates the Secondary Tile. It also can access Marketplace, both to submit a review for the application and to display other applications that are published by me. All in all it is a complete application, yet its functionality is very simple. It is simple enough to explain it almost entirely. That is exactly what I am planning to do over the upcoming weeks.

Initially, the application makes use of code behind. In a later version it will be changed, making use of MVVM and Unit Testing. The application will also act as a sample to show profiling, debugging background agents and many more topics. I will combine blog entries and videos to show how to create this application, how to test it and hopefully how to publish it to Marketplace. As soon as the application is available for download, I will let you know in this blog entry. Here is a sneak preview of EvenTiles.

dump1This application is very simple, yet it contains lots of functionality that you can use inside a Windows Phone application. When the application is started, it checks if a Secondary Tile exists. Actually, it can even be started by clicking on its Secondary Tile when available. If no Secondary Tile is pinned to the start screen, the user has the option to create a Secondary Tile and automatically pin it to the Start Screen. When the Secondary Tile is already pinned on the Start Screen, the user has the possibility to remove it from the Start Screen. You can also see that the application has advertisements. In order to allow for localized advertisements, the application reads the current location of the device once (if the user allows doing that). The application has a Settings Page that can be reached through the ApplicationBar as well as an About Page. To preserve data, the application makes of of Isolated Storage. To transfer data between the application and its background agent, a file in IsolatedStorage is used that is protected by a Mutex. So even though the application itself is very simple, it contains many pieces of functionality that you can use in very complex applications as well. As such, this application is hopefully a starting point that allows you to develop fantastic Windows Phone Applications. Stay tuned for the first part of EvenTiles from Start to Finish – Part 1, which shows you how to create the initial solution and how to create a Secondary Live tile.
