9. App Model: Concepts Application Uniquely identifiable, licensable and serviceable software product packaged as a XAP Application Deployment Steps include Ingestion, Certification and Signing Windows Phone Marketplace Windows Phone Marketplace Application license Crypto-verifiable object issued to grant rights to an application

10. App Lifecycle + • Phone only installs .xap packages signed by marketplace Windows Phone 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

11. App Isolation and Execution Applications and licenses Application install folders Running applications • Phone only runs apps that have a valid marketplace license • Apps are sandboxed into separate security accounts while installed and at runtime • Resource allocation policy keeps the foreground app responsive • Resource management policy ensures the user can always use Start to run a new app

12. App Hosting and Runtime App Domain Silverlight Application Object XNA Game Object Frameworks HTML/JavaScript Silverlight XNA CLR System provides host process for app code App Model Host App Model UI Model Cloud Integration Xbox LIVE Bing Location Push notifications Windows Live ID App management Licensing Chamber isolation Software updates Shell frame Session manager Direct3D Compositor Location Push Notifications Sandbox enforced for host process based on declared capabilities Kernel Hardware BSP A-GPS Accelerometer Compass Light Proximity Media Wi-Fi Radio Graphics Security Networking Storage A-GPS Compass Hardware Foundation • Each app executes inside an isolated, least-privileged host process • All app code is transparent and CLS-verifiable, mitigating impact of common attacks • Frameworks enable app code to interact with app model, UI model, phone functionality

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

18. UI Model: Familiar Web Concepts Phone application Provides UI represented as XAML pages connected into cross-app flows by URI’s Web application Provide media represented as HTTP resources linked by URL’s Shell frame Requests pages, renders UI, and handles navigation across apps Web browser Requests HTTP resources, renders them, and handles navigation across sites Sessions and back stack Groups together sequences of pages corresponding to a user’s activity across apps History and tabs Groups together sequences of HTTP resources corresponding to a user’s activity across sites

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

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

21. 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
