Introduction to Sync FrameworkNew features in Sync Framework 2.0Sync Services for ADO.NETDemo of Sync Services on Windows Mobile client
All stores are differentSome are very capable, most are not
Conflicts are difficult to detectAnd even harder to manage afterwards
Misidentification of conflicts bad experienceDuplicates, over-prompting, data loss
Inefficient change enumeration makes sync too expensive
Sync loops are a fact of lifeFew people set out to get into one, many end up in one
80% solution much simpler than 100%Corner cases are everywhere!
Why use a Framework?Sync is hard

We strike for the balance of power and flexibility
Powerful: solve hard sync problemsConflict detection and resolutionUnreliable networks, i.e. interruptions/partial syncsLoops, metadata loss, etcEasy-to-use and performant
FlexibleArbitrary storesArbitrary protocolsArbitrary data typesArbitrary topologies
Why Microsoft Sync Framework?Solving hard problems exactly once

Writing a Sync Application
SyncOrchestrator orch = new SyncOrchestrator();
orch.LocalProvider = new FileSyncProvider(guid1, “c:\\temp\\
myfolder”);
orch.RemoteProvider =
new LiveMeshProvider(guid2,
new NetworkCreditial(username, password),
“MyMeshFolder”);
orch.Synchronize();
Not too hard!
