  1. Windows Vista:Centralizing Data Synchronization With The New Sync Center David Potter – David.Potter@Microsoft.com DAT317 Development Lead Microsoft Corporation

  2. Agenda • Synchronization Today • Goals for Sync in Windows Vista • New UI Walkthrough • Sync Center Architecture • Building a Sync Handler • Conflicts and Extensibility • Backward Compatibility and Managed Code • Questions

  3. Synchronization Today • Sync Manager provides a centralized UI for sync • Feedback showed us: • UI is hard to discover • Requires user’s attention • Conflicts must be resolved as they occur • Sync blocks logoff • No overview of what is synchronizing to and from the computer • Many applications provided their own sync experiences • Different user interfaces and access points • Sync Manager used mostly for offline files/web pages

  4. Synchronization Today

  5. Sync Goals In Windows Vista • New name – Sync Center • Centralized, consistent sync experience • For applications, services, devices, computers • It is clear to the user what is being synchronized to and from PC • Additional framework for: • Setup • Conflicts • Error reporting • Background sync support

  6. User Experience Walkthrough

  7. Sync Center User Experience5 main components • Sync system tray icon • Folders • Sync Center (handlers and items) • Sync Setup • Sync Results (errors, warnings, etc.) • Conflict Folder

  8. Plugging In To Sync CenterDesign decisions • What is the target of synchronization? • What kinds of data will be synchronized? • How many instances? • What is the setup experience? • Do you need to handle conflicts? • What errors will be reported to users? • Do you need to extend the folder UI? • Do you want to support other tasks?

  12. Sync Handler

  13. Sync Handler ArchitectureSync Handlers

  14. Sync Handler ArchitectureHandler Collections

  15. Synchronization ModelMechanics • Handler interacts with Sync Center through callback • Provides progress • Provides events • Checks for cancellation • Callback created using Session Creator

  16. Synchronization ModelThreading • Previous model • Synchronize() called on same thread as UI • Windows Vista • Handler instantiated on new thread to sync • Synchronize() method can take as long as needed • Less complex model, less work for you!

  17. Sync Model Demo

  18. Background Sync • What is background sync? • Application monitors data source for changes • Automatically syncs in the background • Problem: Status of these syncs not visible to user in centralized UI • Background sync engine should report progress, errors, conflicts to Sync Center • Helps user determine if data is up-to-date

  19. Background Sync Demo

  20. Existing Sync Engine / UI • Use the session creator to plug an existing sync engine into Sync Center • Benefits • You don’t have to refactor your sync engine • Consistent, centralized user experience which includes your sync relationships

  21. ExtensibilitySync Center Folders • Standard shell extensibility model • Property sheets • Context menus • All folder items can be extended • Handlers (partnerships) • Items • Events • Conflicts

  22. ExtensibilityHandlers and Items • Handlers can display additional UI • Confirmation/data collection before operation • Setup, enable, disable, etc. • Sync Center provides entry point for your UI • Scheduling • Browsing contents of sync relationship • Event stores • Conflicts

  23. Conflicts • Conflict definition: • An item that has been changed on both ends of a sync relationship between sync requests • Handler maintains a store of conflicts • Conflict resolution is deferred and does not block sync • Conflict resolution UI • Handler can provide custom conflict UI • Default UI used if not provided by handler

  24. Conflict Resolution UI

  25. Conflict Life Cycle unresolved Detected Persisted enumerateand present automatically resolved skip resolve Resolved Presenting delete Deleted

  26. Compatibility • Windows XP • Write a component to wrap the new APIs • Component translates between new/old APIs • Managed Code • Don’t run managed code in Sync Center or in the Shell • Run managed sync engine in separate process • Design sync handler as intermediary between Sync Center and external sync engine • FUN309 – Designing Managed Add-Ins for Reliability, Security, and Versioning

  27. What’s In The PDC Build • APIs to create a Sync Center handler • All APIs demoed are available • Conflict resolution APIs are available • Primary sync user experience • Sync Center folders with basic functionality • Basic sync tray

  28. What’s In Future Builds • Support for browsing handlers and items • Sync Schedule Wizard • Support for custom event stores • Full sync tray functionality • Fit and finish

  29. Summary • Sync Center is a rich sync platform with APIs that are simple to develop to • Plugging in to Sync Center gives your users a solid sync experience • Sync Center is fully extensible to support a wide-range of sync scenarios
