Finding the Resume type
The Activation handler can test a flag to determine the type of resume taking place
private void Application_Activated(object sender, ActivatedEventArgs e){ if (e.IsApplicationInstancePreserved) { // Dormant - objects in memory intact } else { // Tombstoned - need to reload }}

Isolated Storage vs State Storage Isolated storage is so called because the data for an
application is isolated from all other applications It can be used as filestore where an application can
store folders and files It is slow to access, since it is based on NVRAM
technology It can also be used to store name/value pairs, e.g.
program settings State storage is so called because it is used to hold the
state of an application It can be used to store name/value pairs which are
held in memory for dormant or tombstoned applications
It provides very quick access to data

Fast App Switching and Tombstoning Review Only one Windows Phone application is Active at any
time The Start and Back buttons on the phone are used to
start new applications and return to previously used ones
If an application is replaced by another it is either made Dormant (still in memory but not running) or Tombstoned (removed from memory)
Applications must use populate methods provided in the App.xaml.cs class to save and retrieve state information when appropriate
State can be stored in memory for quick reload and in isolated storage which serve as a permanent store

Windows Phone
Creating a Reminder
This code creates a reminder and adds it as a scheduled service The value eggTime holds the length of the delay This code also sets the url of the page in the application
using Microsoft.Phone.Scheduler;...eggReminder = new Reminder("Egg Timer");
eggReminder.BeginTime = DateTime.Now + new TimeSpan(0, eggTime, 0);eggReminder.Content = "Egg Ready";eggReminder.RecurrenceType = RecurrenceInterval.None;eggReminder.NavigationUri = new Uri("/EggReadyPage.xaml",
UriKind.Relative);
ScheduledActionService.Add(eggReminder);
Windows Phone
Reminder Housekeeping
Reminders are identified by name
This code finds the “Egg Timer” reminder and then removes it from the scheduler
Reminder eggReminder = ScheduledActionService.Find("Egg Timer") as Reminder;
if ( eggReminder != null ) { ScheduledActionService.Remove("Egg Timer");}
