Indicates whether the application instance was preserved.
Assembly: Microsoft.Phone (in Microsoft.Phone.dll)
When an application is deactivated, it is typically put into a dormant state. In this state, although no code is executed, the application state is preserved intact in memory. When an application is activated from being in a dormant state, it resumes automatically and does not need to reestablish its state. It is possible, however, for an application to be tombstoned after being placed into a dormant state. In this case, the application is not stored in memory, although state information can be stored in the application and page State dictionaries. When an application is activated after being tombstoned, it will need to re-create its previous state. For more information, see Execution Model Overview for Windows Phone.
