Properties

	Name	Description
	Configuration	When overridden in a derived class, gets a KnowledgeSyncProviderConfiguration object that represents configuration information for a provider, such as the conflict resolution policy. (Inherited from SimpleSyncProvider.)
	DestinationCallbacks	When overridden in a derived class, gets a SyncCallbacks object that is used to dispatch a synchronization event. (Inherited from SimpleSyncProvider.)
	IdFormats	When overridden in a derived class, gets a SyncIdFormatGroup object that represents the format of replica and item IDs. (Inherited from SimpleSyncProvider.)
	MetadataSchema	When overridden in a derived class, gets an ItemMetadataSchema object that represents the metadata schema for an item. (Inherited from SimpleSyncProvider.)
	ProviderVersion	When overridden in a derived class, gets the version number for the simple provider. (Inherited from SimpleSyncProvider.)

Methods

	Name	Description
	BeginSession	When overridden in a derived class, called by the Sync Framework runtime at the start of each session. (Inherited from SimpleSyncProvider.)
	DeleteItem	When overridden in a derived class, called by the Sync Framework runtime to delete an item from the destination store. (Inherited from SimpleSyncProvider.)
	EndSession	When overridden in a derived class, called by the Sync Framework runtime at the end of each session unless a session is terminated because of an exception. (Inherited from SimpleSyncProvider.)
	EnumerateChanges	When overridden in a derived class, enumerates changes from a replica that occurred since the specified anchor value.
	Equals	(Inherited from Object.)
	Finalize	(Inherited from Object.)
	GetEnumerationAnchor	When overridden in a derived class, returns an enumeration anchor that is used to determine the set of changes to synchronize during a session.
	GetHashCode	(Inherited from Object.)
	GetMetadataStore	When overridden in a derived class, called by the Sync Framework runtime to return a MetadataStore object for a replica. (Inherited from SimpleSyncProvider.)
	GetType	(Inherited from Object.)
	InsertItem	When overridden in a derived class, called by the Sync Framework runtime to insert an item into the destination store. (Inherited from SimpleSyncProvider.)
	LoadChangeData	When overridden in a derived class, called by the Sync Framework runtime to load the change data for the item with the specified key. (Inherited from SimpleSyncProvider.)
	MemberwiseClone	(Inherited from Object.)
	OnChangeDetectionCompleted	When overridden in a derived class, raises the ChangeDetectionCompleted event. (Inherited from SimpleSyncProvider.)
	OnItemConflicting	When overridden in a derived class, raises the ItemConflicting event. (Inherited from SimpleSyncProvider.)
	OnItemConstraint	When overridden in a derived class, raises the ItemConstraint event. (Inherited from SimpleSyncProvider.)
	OnMetadataStoreInitialized	When overridden in a derived class, raises the MetadataStoreInitialized event. (Inherited from SimpleSyncProvider.)
	ToString	(Inherited from Object.)
	UpdateItem	When overridden in a derived class, called by the Sync Framework runtime to update an item in the destination store. (Inherited from SimpleSyncProvider.)

Events

	Name	Description
	ChangeDetectionCompleted	Occurs when change detection is complete for a source provider. (Inherited from SimpleSyncProvider.)
	ItemConflicting	Occurs when Sync Framework detects that an item being processed is involved in a concurrency conflict. (Inherited from SimpleSyncProvider.)
	ItemConstraint	Occurs when Sync Framework detects that an item being processed is involved in a constraint conflict. (Inherited from SimpleSyncProvider.)
	MetadataStoreInitialized	Occurs when the metadata store that is associated with a provider is initialized. (Inherited from SimpleSyncProvider.)

Remarks

The simple provider API is designed primarily for two types of replicas:

• Replicas that do not support any kind of change tracking. This type of replica uses a full enumeration provider (FullEnumerationSimpleSyncProvider), which enumerates all items from the source replica every time synchronization occurs.

• Replicas that support anchor-based change tracking. This type of replica uses an anchor-based provider (AnchorEnumerationSimpleSyncProvider), which enumerates the items from the source replica that changed after a specific anchor was set, which is typically a point in time.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
