  5. Agenda

  6. Local database Your App Custom Data Context App Objects • SQL CE 4 • Sandboxed • LINQ to SQL System.Data.Linq Object Materialization Identity Management Change Tracking Update Processing Microsoft.Phone.Data.Internal Core ADO.NET (System.Data) SQL CE DB SQLCE ADO.NET Provider (System.Data.SqlServerCe)

  7. SQL CE CODE WALK-THROUGH

  8. LINQ To SQL Mapping Attributes

  9. Lessons and tips • MS recommends code first approach • Design object model • Apply Attributes • SQL Metal works too • Leverage background threads • Keep changes small (aka save often) • Let SQL do the work

  10. Multi-tasking design principles Delightful and Responsive UX Battery Friendly Health Never Regret App Install Network Conscience UX Integrated Feel Hardened Services

  11. Multi-tasking Options • Background Transfer Service • Background Audio • Background Agents • Periodic • On Idle • Alarms and Reminders

  12. Background Transfer Service • Start in foreground, complete in background, even if app is closed • Queue (of 5) persists across reboots • Single service for many apps, FIFO • Download ~20 MB ( > over Wi-Fi) • Upload Size ~4 MB (limit to come) • Transfers to Isolated Storage

  13. Background Transfer CODE WALK-THROUGH

  14. Notifications • Time-based, on-phone notifications • Supports Alerts & Reminders • Persist across reboots • Adheres to user settings • Consistent with phone UX

  15. Alarms vs Reminders? • Alarms • Reminders • Rich information • Integrates with other reminders • Snooze and Dismiss • Launch app • Follows the phones global settings • Modal • Snooze and Dismiss • Sound customization • No app invocation • No stacking

  16. Reminders CODE WALK-THROUGH

  17. Live Tile improvements • Local Tile APIs • Full control of ALL properties • Multiple tiles per app • Create,Update/Delete/Query • Launches direct to Uri Secondary Tile Launches local news page Application Tile Launches main app experience Secondary Tile Launches world news page

  18. Live Tiles – Local Tile API (2) • Back of tile updates • Full control of all properties when your app is in the foreground or background • Content, Title, Background • Flips from front to back at random interval • Smart logic to make flips asynchronous Content Content string is bigger Background Title Title

  19. Live tiles CODE WALK-THROUGH

  20. Generic Agents Periodic Agents • Occurrence • Every 30 min • Duration • ~15 seconds • Constraints • <= 5 MB Memory • <=10% CPU On Idle Agents • Occurrence • External power, non-cell network • Duration • 10 minutes • Constraints • <= 5MB Memory All of this is requirements can change before RTM, but should not change too much

  21. Background Agent Functionality Allowed Restricted • Tiles • Toast • Location • Network • R/W ISO store • Sockets • Most framework APIs • Display UI • XNA libraries • Microphone and Camera • Sensors • Play audio(may only use background audio APIs)

  22. Background Agents CODE WALK-THROUGH

  23. Background Tips & Lessons • Renew often • Known issues in beta build • SQL CE & memory • Debugger (prompts & memory) • IsEnabled flag • One agent for multiple tasks

  24. A “Mango” to-do app.. • Local database + LINQ to SQL • Alarms and Reminders • Live tiles (secondary tiles) • Navigation • Background processing • FAS, File transfer, Agents

  25. Take on the challenge!! • Windows Phone “Mango” Training Kit http://bit.ly/WP7MangoKit • Tidy Labs: • SQL, • Tiles • BTS • Background Agents • Other labs • Photo fun • SL + XNA • Choosers & Launchers • Push
