This namespace contains types that are used for client and server and peer-to-peer synchronization in Sync Services for ADO.NET. The following namespaces are used in client and server synchronization: Microsoft.Synchronization, Microsoft.Synchronization.Data, Microsoft.Synchronization.Data.Server, and Microsoft.Synchronization.Data.SqlServerCe. The following namespaces are used in peer-to-peer synchronization: Microsoft.Synchronization and Microsoft.Synchronization.Data.

	DbSyncScope	Represents a logical grouping of objects to be synchronized.
	DbSyncScopeMetadata	Represents the metadata for a DbSyncScope object, such as the knowledge that is associated with a particular scope.
	DbSyncScopeProgress	Represents a set of synchronization progress statistics for the objects in a DbSyncScope.
	DbSyncSession	Represents a synchronization session. The DbSyncSession object exists for the duration of the synchronization session.

	SyncConflict	Represents a synchronization conflict at the row level.
	SyncConflictResolver	Represents the actions to take when any conflicts occur during synchronization.
	SyncContext	Encapsulates data changes and anchor values and other metadata for a synchronization session.
	SyncGroup	Represents a group of SyncTable objects and provides a mechanism to ensure consistent application of changes for those tables.
	SyncGroupMetadata	Represents the metadata for a SyncGroup object, such as the new anchor value.
	SyncGroupProgress	Represents a set of synchronization progress statistics for the tables in a SyncGroup.
	SyncParameter	Encapsulates information sent from the client to the server.
	SyncParameterCollection	A collection of SyncParameter objects.
	SyncProgressEventArgs	Provides data for the client SyncProgress event and the server SyncProgress event.
	SyncSchema	Represents the schema information that is required to create tables that are involved in synchronization.
	SyncSchemaColumn	Represents the schema of a column in a SyncSchemaTable.
	SyncSchemaColumns	Represents a collection of SyncSchemaColumn objects.
	SyncSchemaForeignKey	Represents a foreign key relationship between two tables that are involved in synchronization.
	SyncSchemaForeignKeys	Represents a collection of SyncSchemaForeignKey objects.
	SyncSchemaTable	Represents the schema of a table that is involved in synchronization.
	SyncSchemaTables	Represents a collection of SyncSchemaTable objects.
	SyncSession	Represents a synchronization session. The SyncSession object exists for the duration of the synchronization session.
	SyncStatistics	Represents a summary of a SyncSession with regard to the total number of operations that occurred on the client and server.
	SyncTable	Represents the client settings for a table involved in synchronization.
	SyncTableCollection	Represents a collection of SyncTable objects.
	SyncTableInfo	Encapsulates information about table settings and metadata. This information is available through GetServerInfo.
	SyncTableMetadata	Encapsulates the metadata that is associated with a SyncTable, such as the direction of synchronization.
	SyncTableProgress	Represents a set of synchronization progress statistics for a SyncTable object.
	SyncTracer	Provides tracing for a synchronization session, with four levels of output: errors, warnings, informational, and verbose.
