I get this using SL 4 and RIA Services trying to save images to SQL Server using the Entity framework. The first few SubmitChanges() works then it fails with the above. Using fiddler I get the following:
System.ServiceModel.CommunicationException: Unrecognized message version.
at System.ServiceModel.Channels.ReceivedMessage.ReadStartEnvelope(XmlDictionaryReader
reader)
at System.ServiceModel.Channels.BufferedMessage..ctor(IBufferedMessageData
messageData, RecycledMessageState recycledMessageState, Boolean[]
understoodHeaders)
at System.ServiceModel.Channels.BinaryMessageEncoderFactory.BinaryMessageEncoder.ReadMessage(ArraySegment1
buffer, BufferManager bufferManager, String contentType)
at System.ServiceModel.Channels.MessageEncoder.ReadMessage(ArraySegment1
buffer, BufferManager bufferManager)
at BinaryMessageFiddlerExtension.BinaryInspector.GetWcfBinaryMessageAsText(Byte[]
encodedMessage)
at BinaryMessageFiddlerExtension.BinaryInspector.UpdateView(Byte[] bytes)
As I am saving images to the database and it works Intermittently, is this probably a timeout error?
