Back to basics - simple Azure table test results

What happens if you try to create an object twice:

            CloudTableClient client = new CloudTableClient(

                "https://thing.table.core.windows.net",

                new StorageCredentialsAccountAndKey("thing", "****blurb******"));

            client.CreateTableIfNotExist("TestData");

            var context1 = client.GetDataServiceContext();

            Thing t = new Thing();

            t.PartitionKey = "Fred";

            t.RowKey = "Bloggs";

            t.TestField = "test";

            context1.AddObject("TestData", t);

            var response = context1.SaveChanges();

            context1.Detach(t);

            context1.AddObject("TestData", t);

            response = context1.SaveChanges();

the answer... is that you get an exception thrown in the second "SaveChanges()" - the exception is System.Data.Services.Client.DataServiceRequestException - with an InnerException of type DataServiceClientException -with StatusCode 409 - EntityAlreadyExists
