  2. Changing our GameA new approach with WP7 DESIGN: END USER COMES FIRST PLATFORM: RICHER, DEEPER, EASIER APPS HARDWARE: FASTER TO MARKET, LESS HEAVY LIFTING

  3. Session Outline Cloud Integration Services App Model UI Model Software Architecture Hardware Foundation

  4. Cloud Integration Services App Model UI Model Software Architecture Hardware Foundation

  5. Hardware Foundation Capacitive touch 4 or more contact points 800 or 480 Sensors A-GPS, Accelerometer, Compass, Light, Proximity Camera 5 mega pixels or more Multimedia Common detailed specs, Codec acceleration Memory 256MB RAM or more, 8GB Flash or more GPU DirectX 9 acceleration CPU ARMv7 Cortex/Scorpion or better Hardware buttons | Back, Start, Search 480 or 320

  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

  22. DEMO: UI MODEL

  23. 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 • System wide Z order enforcement emphasizes core phone functionality

  24. Graphics Architecture App UI and logic Silverlight XNA HTML/JavaScript Shell frame Compositor Direct3D Window manager Graphics driver

  26. Cloud Integration: Concepts Windows Phone Your Web Service Custom Web Service Windows Phone Application Existing Web Services Notification Service Location Service Microsoft Services Frameworks Cloud integration client services • Built-in user experiences and APIs integrated with key Microsoft services • Familiar API frameworks for interacting with existing Web 2.0 services • Rich support for incorporating custom web services into app-specific experiences

  27. Location Service Windows Phone Existing Web Services Location Service Microsoft Services System.Device.Location Location client service • Built-in support for consuming GPS, AGPS and Wi-Fi- based location data • Managed APIs for location-based interaction • Microsoft managed Wi-Fi access point data as part of Windows Phone Services

  28. Location Client Architecture Microsoft Services Windows Phone Location Service App UI and logic Location client service Security A-GPS Wi-Fi Radio

  29. Push Notification Service Windows Phone Your Web Service Custom Web Service Existing Web Services Notification Service Microsoft Services Microsoft.Phone.Notification Push client service • Built-in support for efficient, battery-aware mobile push notifications • Managed APIs for notification-driven interaction with existing Web 2.0 sites

  30. Push Client Architecture Microsoft Services Microsoft Push Notification Service App UI and logic Microsoft.Phone.Notification Live Tiles service Download Manager Push client service Networking Wi-Fi Radio

  31. DEMO: PUSH NOTIFICATION

  32. XBOX Live Windows Phone Your Web Service Game specific web requests Custom Web Service Microsoft Services Authenticated Xbox LIVE calls XNA Game Foundation • Gamer Services APIs for Xbox LIVE Profiles, Achievements, and Leaderboards • Game Foundation handles auth, caching, & partial connectivity for Xbox LIVE • Third party token allows secure integration with game-specific services
