When you create a new entity using an OData v3 connection and then call this.SaveChanges(), it saves the entity and its state is set to Unchanged. Then, calling this.GetOperationDescriptor(myEntity).OperationDescriptors returns 0 elements, but calling the same code using a Service Reference in VS2013 does return all the operation descriptors. It would be nice if LINQPad couild have the same behaviors because, looking at the response in Fiddler, the links are returned in the response but they are just ignored.
