	GetHashCode	(Inherited from Object.)
	GetSchema	Gets the table schema from the server database. (Overrides ServerSyncProvider.GetSchema(Collection<String>, SyncSession).)

Remarks

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.

Examples

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.
