(2) Changing our Game A new approach with WP7. DESIGN:. PLATFORM:. HARDWARE:. END USER COMES FIRST. RICHER, DEEPER, EASIER APPS. 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. Sensors A-GPS, Accelerometer, Compass, Light, Proximity. Camera. 800 or 480. 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. Application license Crypto-verifiable object issued to grant rights to an application. Windows Phone Marketplace.

(10) App Lifecycle. Windows Phone Marketplace. +. 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.

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

(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. Web application. Provides UI represented as XAML pages connected into cross-app flows by URI’s. Provide media represented as HTTP resources linked by URL’s. Shell frame. Web browser. Requests pages, renders UI, and handles navigation across apps. 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. Pictures Continue looking at recent photos. Active sessions.

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

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