I am sure every Windows Phone user would have heard the word “Tombstoning” when developing a Windows Phone App.
What is Tombstoning in Windows Phone?
When a Windows Phone Application is terminated, the data about the page or application is saved and preserved. When the user Navigates to the Application, the App is created again and the data saved is restores automatically.
For example, when you are working on a Page X, you hit the Windows Key, at this point of time, the application is sent to dormant state.
Now when you launch the Application again from the Home Screen or App Screen, the App is recreated. At this point of time, we try to retain the last saved data on to the App screen.
