The ServerSyncProviderProxy type exposes the following members.


  Name Description
Public method ServerSyncProviderProxy Initializes a new instance of the ServerSyncProviderProxy class by using a service proxy parameter.



  Name Description
Public method ApplyChanges Applies inserts, updates, and deletes for a synchronization group to the server database. (Overrides ServerSyncProvider.ApplyChanges(SyncGroupMetadata, DataSet, SyncSession).)
Public method Dispose Releases all resources that are used by the ServerSyncProviderProxy. (Overrides ServerSyncProvider.Dispose().)
Public method Equals (Inherited from Object.)
Protected method Finalize (Inherited from Object.)
Public method GetChanges Selects for a table in the server database the inserts, updates, and deletes to apply to the client database for a synchronization group. (Overrides ServerSyncProvider.GetChanges(SyncGroupMetadata, SyncSession).)
Public method GetHashCode (Inherited from Object.)
Public method GetSchema Gets the table schema from the server database. (Overrides ServerSyncProvider.GetSchema(Collection<String>, SyncSession).)
Public method GetServerInfo Gets server synchronization information. (Overrides ServerSyncProvider.GetServerInfo(SyncSession).)
Public method GetType (Inherited from Object.)
Protected method MemberwiseClone (Inherited from Object.)
Public method ToString (Inherited from Object.)



The ServerSyncProviderProxy class is used in N-tier scenarios: The proxy class is used on the client, and the server synchronization provider class is used on the server or on a middle-tier. The proxy communicates with a service on the server or middle-tier, and the service in turn communicates with the server synchronization provider.


The following code example is from a class that derives from SyncAgent. For two-tier synchronization, the client provider and server provider are both referenced directly in the synchronization agent as local and remote providers.

this.LocalProvider = new SampleClientSyncProvider();

this.RemoteProvider = new SampleServerSyncProvider();
Me.LocalProvider = New SampleClientSyncProvider()

Me.RemoteProvider = New SampleServerSyncProvider()

The following code example references the client provider directly, as in the two-tier example. However, the remote provider now references a proxy instead of directly referencing the server provider. The proxy is created by passing a reference to a WCF service. For more information, see How to: Configure N-Tier Synchronization.

this.LocalProvider = new SampleClientSyncProvider();

ServiceReference.ServiceForSyncClient serviceProxy = new ServiceReference.ServiceForSyncClient();
this.RemoteProvider = new ServerSyncProviderProxy(serviceProxy);
Me.LocalProvider = New SampleClientSyncProvider()

Dim serviceProxy As New ServiceReference.ServiceForSyncClient()
Me.RemoteProvider = New ServerSyncProviderProxy(serviceProxy)

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.
