App Lifecycle
+
Phone only installs .xap packages signed by marketplace
Phone handles all aspects of .xap installation based on the manifest
Individual apps cannot make arbitrary changes to the phone during installation
Users control install, update and uninstall, while the marketplace controls revocation
Individual apps do not control their own lifecycle on the phone

DEMO
Basic Application Development

App Model
UI Model
Hardware Foundation

Application
UI and logic for functionality exposed through pages
UI Model: Concepts
Page
A single screen of user interaction elements
Session
An ordered workflow of user interactions spanning applications

Pictures
Take a look at recent photos
People
Look up the status for a contact
Active sessions
Pictures
Continue looking at recent photos
UI Navigation: Example

Page UI
Describes the visual appearance of a page
Retained in shell frame to support resuming paused sessions
Discarded while the session is paused
UI and State Management: Concepts
Page State
Contains data that describes an instance of a page, analogous to browser cookie

UI and State Management: Example
Running Applications
Dehydrated and rehydrated on demand from saved state
Apps restarted and UI rehydrated as the user navigates thru the phone
Shell Frame
Monitors resource usage to decide when to pause sessions

Graphics Composition
Start Experience
System Tray
Direct3D Surface
AppPage
Notification
Volume
SIP
Incoming Call
App Bar
Shell frame composes all UI into a single screen
Central page management enables cross app UI transitions and other effects
