Developing Mobile Code Today that will run on Windows Phone 7 Tomorrow

1. Required Slide SESSION CODE: WPH311 Developing Mobile Code Today that will run on Windows Phone 7 Tomorrow Khalid Siddiqui Senior Architect, Mobility Center of Excellence Microsoft Corporation

2. Session Objectives • Learn techniques to get maximum reuse out of your code • Learn how to build occasionally connected applications today that will work tomorrow Key Takeaway The session will help you to plan for coexistence between the two windows phone platforms

3. Elements of the Application Platform Tools Runtime – On “Screen” Phone Emulator Sensors Media Data Location Samples Documentation Phone Xbox LIVE Notifications Guides Community .NET Framework managed code sandbox Packaging and Verification Tools SCREEN CLOUD Portal Services Cloud Services Notifications App Deployment Registration Marketplace Validation MO and CC Billing Location Identity Feeds Certification Business Intelligence Social Maps Publishing Update Management

4. Development Environment Up to 5 installs, finding the right versions for each component One Install containing a tuned set Developer tools

5. Application Environment

6. Do I have these WM6.5 Features? • Data • SQL CE • File system Access • Communication • RAPI • IPC • Sockets • Application Access to Bluetooth • Code Access • Access to Privileged API’s • Native Code • Device Management • CAB Installation • Others • Flash Player • WinForms • Widgets

7. Why were these changes made? • User Experience • New Development Platform • Sandbox Model • Foundation for “Three Screen Strategy” • Shift to Cloud based services • Targeting a larger audience

8. Shifting Development Strategies Classic Development • Forward Looking Web + Services Application + Services Application – Oriented around one device (1 Screen) Oriented around multiple devices (x Screens)

9. Development Environment DEMO

10. Application Lifecycle Considerations • Planning • Development • Presentation Layer • Data Services • Deployment • Installation • Updates • Provisioning • Management

11. Presentation Layer • Follow Silverlight Roadmap • WM6.5 Controls vs. Silverlight Controls • Use minimal code on pages • Use Expression Blend Sketch Flow for UI creation

12. Model View Controller Pattern • Model • Objects representing data • Corresponding Domain logic • Business rules and validation • View – User Interface • Controller • Communication from the user • Application flow • Application specific logic Also see MVVM pattern

13. Data Persistence

14. Data Synchronization • Sync Framework • Hosted Push Notifications • Save Application state frequently • Pause Event • Obscured Event • Avoid Merge Replication or RDA

15. Sync Framework • Provider based framework for the sync across various source and depots. • All central based sync • No sync run on the device, cloud takes care of all data differences • With Nov Power Pack a SQL Azure provider was added as CTP • Will be supported on WP6.5 • Only supported Sync technology in WP7 as of today • Open Data Protocol (oDATA) • Useful Link: http://msdn.com/sync

16. Offline / Cache Mode Apps End to End Sync smarts on server, not on client Easy to develop the sync endpoints Simple sync protocol (OData-Sync) Windows Azure Sync FX Sync Endpoints Other Platforms Store Sync Auth / Mgmt / Bus Logic Richer UX & Capabilities Minimal client & store requirements Reach Sync Sync Sync Client API support . Windows Silverlight HTML

17. Push Notification • WP7Application Platform provides a set of managed API’s • Allow developers to directly connect applications to on-line services • API’s support a push model of notifications instead of polling

18. Push Notifications Tile Push client Toast Open push channel Data to toast Data to tile Return URI Data to App App Send URI to server Send push data to client Push service Your service Event Send push data to URI

19. Deployment • WP 7 requires Marketplace • WP 6.x has Marketplace available • Can your application move to Marketplace?

20. Windows Phone Applications DEMO

21. Summary Section

22. Industry Practices • Plan for Porting Applications to WP7 • Managed Code only • Persist data in preparation for application pause • Follow Silverlight and XNA roadmap • Use Marketplace, if feasible • Avoid file system access or using sockets • Use Cloud based Services • Notifications • Data Storage • Sync Framework • Let application query for updates • Use Model View Controller pattern, as needed • Get familiar with Azure based applications

23. Platform Decision – WP 6.5 or WP 7 • Is there a problem in exposing your application to Marketplace for Distribution? • Is encryption required? • Is managed device a requirement? • Any special device requirements like ruggedized device?
