Tombstoning and Task Switching - Day 3 - Part 8
How does your application respond when a user clicks the Start button or Back button on Windows Phone 7? In this video, Bob explains the difference between the Launched, Activated, Closed, and Deactivated events, how your application can be notified via event handlers in the App.xaml.cs code-behind file, and how to take that opportunity to save the current state of the application. Then, once the user has re-launched the applications, the state information can be retrieved and the state of the application from the previous session can be restored. Bob also explains how a special feature of Isolated Storage called IsolatedStorageSettings can provide an easy way to save name / value pair information without having to create and access a text file.
