How to: Add, Modify, and Delete Entities (WCF Data Services) .NET Framework (current version) Other Versions WCF Data Services 5.0 Visual Studio 2010 .NET Framework 4 .NET Framework 3.5 With the WCF Data Services client libraries, you can create, update, and delete entity data in a data service by performing equivalent actions on objects in the DataServiceContext. For more information, see Updating the Data Service (WCF Data Services).The example in this topic uses the Northwind sample data service and autogenerated client data service classes. This service and the client data classes are created when you complete the WCF Data Services quickstart.ExampleThe following example creates a new object instance and then calls the AddObject method on the DataServiceContext to create the item in the context. An HTTP POST message is sent to the data service when the SaveChanges method is called. C#VB Copy // Create the DataServiceContext using the service URI.

Background/Suspected Cause: Load balancer! - We recently changed our infrastructure so that our web servers now sit behind a load balancer which also handles implementing a wcf the ssl. Clients address the service as HTTPS but IIS ends up processing HTTP requests since the SSL was done by the load balancer(I am sure most of you are familiar with this type of setup). Anyway, what we end up with is a feed that contains URIs that are using HTTP rather than HTTPS. (see GET request/response below with http in the response instead of httpS). The behavior is pretty strange, as when I call saveChanges() it sends a MERGE(as expected), and I get back a 302: HTTP/1.1 302 Object moved Location: https://some.domain.org/CMSProfileService/ProfileDataService.svc/Mails(guid'80fef993-a4b5-4343-a908-28c2c6517a81') Connection: close but WCF keeps trying the MERGE over and over using HTTP(about 50 times) then finally throws an exception with the message, ""An error occurred while processing this request.", inner excepion message is "Found". :) When I point directly at the server(bypassing the loadbalancer and ssl) everything works fine. Everything also works fine when SSL is registered directly in IIS. There must be some config setting/property that I am not finding. Viteks answer to a similar question scares me a bit. This is the
