Потоковая служба .net WCF MVVM

---

У меня есть приложение MVVM WPF, которое я пытаюсь загрузить большой байт[] на сервер для хранения в стабильном состоянии, но сталкиваюсь с несоответствием содержимого и запросом слишком больших ошибок. Я перешел к использованию возможности потока в веб-службе, но не уверен, что у меня есть правильный клиентский код.

//Client Code
           try
            {
                string strCertLetterLogID = string.Empty;
                Microsoft.Office.Interop.Word.Document oDocument = Globals.ThisAddIn.Application.ActiveDocument;
                oDocument.Save();
                strCertLetterLogID = GetCertLetterLogID(oDocument);
                byte[] docData = Library.Helpers.FileUtils.ReadFile(oDocument.FullName);
                //byte[] docData = new byte[300];
                Globals.ThisAddIn.Application.StatusBar = string.Format("Sending {0} bytes to update Certifitrac letter {1}.", docData.Length.ToString(), oDocument.FullName);
                if (!string.IsNullOrEmpty(strCertLetterLogID))
                {
                    //DTP.Data.CertLetterLog param = new DTP.Data.CertLetterLog
                    //{
                    //    CertLetterLogID = Guid.Parse(strCertLetterLogID),
                    //    DocumentData = docData, //Library.Helpers.FileUtils.ReadFile(oDocument.FullName),
                    //    CertLetterLogType = (int)Library.DocumentOutput.Output.OutputType.RTF,
                    //    CertLetterLogDate = DateTime.Now
                    //};

                    tmpRequest.Stream = new MemoryStream(docData);

                    using (FileStream fStream = new FileStream(oDocument.FullName,FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
                    {
                        wcfClient.Upload(tmpRequest.CertLetterLogID, tmpRequest.FileName, tmpRequest.Stream, out xferStatus);
                    }
