Unable to consume ADO.NET Data Services from Silverlight.

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :WCF
Hi Everyone, I am having trouble consuming an ADO.NET Data Service from Silverlight.  I am able to get data back from a browser, but not in Silverlight. I am at a loss to figure this out.  Any help is much appreciated.  Let me know if you need more info. Thank you in advance for any help! Here is the the silverlight code: private Uri svcUri = new Uri("http://localhost:64522LocalTariffsDataService.svc"); private void ctrlViewLocalTariffs_Loaded(object sender, RoutedEventArgs e) { svcContext = new LocalTariffEntities(svcUri); svcContext.LocalTariffs.BeginExecute(OnLocalTariffsQueryCompleted, svcContext.LocalTariffs); } private void OnLocalTariffsQueryCompleted(IAsyncResult result) { Dispatcher.BeginInvoke(() => { DataServiceQuery<LocalTariffsEntityDataService.LocalTariff> query = result.AsyncState as DataServiceQuery<LocalTariffsEntityDataService.LocalTariff>; LocalTariffsEntityDataService.LocalTariff returnedLocalTarrifs = query.EndExecute(result).FirstOrDefault(); // Exception is thrown here. dgLocalTariffs.DataContext = returnedLocalTarrifs; }); } Here is the exception: < E2ETraceEvent xmlns = " http://schemas.microsoft.com/2004/06/E2ETraceEvent " >
