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

  12. App Deployment and Update + • 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

  13. Application Lifecycle • Splash screen • App constructor • Startup event • Exit event • Obscured by shell • Moved to background

  14. App Lifecycle : Obscured • Phone call • Reminder • Battery low Applications enable user to resume What if they answer the phone? • Application is automatically paused • Shell UI Obscures application UI

  15. Application Lifecycle: Deactivate & Activate • We’ll cover “background processing” in the future • You will get more details from Peter’s talk on Wednesday • Hit Start • Open toast • Lock screen User is back where they left off Load state to continue where you left off Save state for later use Assume your process is killed

  16. App Isolation and Execution Application install folders Applications and licenses 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

  17. App Hosting and Runtime App Domain Silverlight Application Object XNA Game Object Frameworks Silverlight XNA HTML/JavaScript CLR App Model Host • System provides host process for app code 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 Kernel Push Notifications Hardware BSP Security Networking Storage • Sandbox enforced for host process based on declared capabilities A-GPS Accelerometer Compass Light Proximity Media Wi-Fi Radio Graphics 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, and phone functionality

  18. Windows Phone 7 Framework At-a-Glance Common .NetClass Libraries Device and Phone Capabilities Silverlight Presentation and Media Library Cloud Services Integration Windows Phone 7 Framework XNA Framework Windows Phone App and UI Model Xbox LIVE Services Windows Phone Controls

  20. Building a Windows Phone 7 Application using Visual Studio Name: Soumitra SenguptaCompany: Microsoft Corporation DEMO

  21. 3 Screens and Cloud Cloud Windows Desktop Xbox Windows Phone XNA Framework XNA Framework XNA Framework Location Service Notification Service Silverlight Presentation and Media Silverlight Presentation and Media Windows Phone 7 Windows Phone 7 Series Frameworks Windows Phone 7 Common .Net Class Libraries

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

  23. 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

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

  25. 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

  26. 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

  27. UI and State Management: Concepts 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

  28. Windows Phone 7 Page Navigation Name: Soumitra SenguptaCompany: Microsoft Corporation DEMO

  29. Graphics Composition Direct3D Surface AppPage Start Experience System Tray Incoming Call Notification Volume SIP 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

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

Cloud Integration: Concepts Your Web Service Windows Phone Custom Web Service Windows Phone Application Existing Web Services Notification Service Location Service Microsoft Services Frameworks Cloud integration client services Windows Phone 7 Windows Phone 7 • 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

  33. Location Service Windows Phone Existing Web Services Location Service Microsoft Services System.Device.Location Windows Phone 7 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

  34. Location Client Architecture Microsoft Services Windows Phone Location Service App UI and logic Silverlight XNA HTML/JavaScript Location client service Security A-GPS Wi-Fi Radio

  35. Push Notification Service Windows Phone Your Web Service Custom Web Service Existing Web Services Notification Service Microsoft Services Windows Phone 7 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

  36. Push Notification Service 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

  37. Xbox LIVE Your Web Service Windows Phone 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, and partial connectivity for Xbox LIVE • Third party token allows secure integration with game-specific services
