JScript does not support passing value-type arguments by reference.

Parameters

  • itemData
    Data for the item in a provider-specific format.
  • changeUnitsToMerge
    A collection of SyncId objects that represent a set of change units that should be merged during conflict resolution.
  • changeUnitsToUpdate
    A collection of SyncId objects that represent a set of change units that should be updated during conflict resolution.
  • keyAndExpectedVersion
    The key and version properties of the item that is in conflict.
  • recoverableErrorReportingContext
    A RecoverableErrorReportingContext object that is used to report recoverable errors that occur during attempts to resolve a conflict.
  • updatedVersion
    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.

Exceptions
