Assembly: System.Data.Services.Client (in System.Data.Services.Client.dll)
The following example retrieves and modifies an existing object and then calls the method on the DataServiceContext to mark the item in the context as updated. An HTTP MERGE message is sent to the data service when SaveChanges is called. This example uses the DataServiceContext generated by the Add Service Reference tool based on the Northwind data service, which is created when you complete the WCF Data Services quickstart.
