Parameters

• itemData
  Type: System.Object
  Data for the item in a provider-specific format.

• changeUnitsToMerge
  Type: System.Collections.Generic.IEnumerable<SyncId>
  A collection of SyncId objects that represent a set of change units that should be merged during conflict resolution.

• changeUnitsToUpdate
  Type: System.Collections.Generic.IEnumerable<SyncId>
  A collection of SyncId objects that represent a set of change units that should be updated during conflict resolution.

• keyAndExpectedVersion
  Type: Microsoft.Synchronization.SimpleProviders.ItemFieldDictionary
  The key and version properties of the item that is in conflict.

• recoverableErrorReportingContext
  Type: Microsoft.Synchronization.SimpleProviders.RecoverableErrorReportingContext
  A RecoverableErrorReportingContext object that is used to report recoverable errors that occur during attempts to resolve a conflict.

• updatedVersion
  Type: Microsoft.Synchronization.SimpleProviders.ItemFieldDictionary%
  Returns the updated version properties of the updated items. If the return value is invalid, the Sync Framework runtime throws ArgumentOutOfRangeException, which ends the session.
