WCF Streaming issue with ASP.NET

Question

I have a WCF service hosted in a ASP.NET application and am trying to upload a file from another client ASP.NET application using streaming mode. I keep getting following error:

The remote server returned an unexpected response: (400) Bad Request.

I have browsed the net to get help but to no avail.

Host configuration:

    <bindings>
      <basicHttpBinding>
        <binding name="FileTransferServicesBinding"
          transferMode="Streamed"
          messageEncoding="Mtom"
          sendTimeout="01:05:00"
          maxReceivedMessageSize="10067108864">
        </binding>
      </basicHttpBinding>
    </bindings>
    <services>
      <service behaviorConfiguration="FileTransferServiceBehavior" name="WebServiceHost.TransferService">
        <clear />
        <endpoint address="" binding="basicHttpBinding"
          bindingConfiguration="FileTransferServicesBinding" contract="WebServiceHost.ITransferService">
          <identity>
            <dns value="localhost"/>
            <certificateReference storeName="My" storeLocation="LocalMachine"
                x509FindType="FindBySubjectDistinguishedName" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange">
        </endpoint>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:11291/TransferService.svc" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="FileTransferServiceBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

Contracts code:

[ServiceContract]
public interface ITransferService
{
    [OperationContract]
    RemoteFileInfo DownloadFile(DownloadRequest request);

    [OperationContract]
    void UploadFile(RemoteFileInfo request);

    [OperationContract]
    string TestMethod();
}

[MessageContract]
public class DownloadRequest
{
    [MessageBodyMember]
    public string FileName;
}

[MessageContract]
public class RemoteFileInfo : IDisposable
{
    [MessageHeader(MustUnderstand = true)]
    public string FileName;

    [MessageHeader(MustUnderstand = true)]
    public long Length;

    [MessageBodyMember(Order = 1)]
    public System.IO.Stream FileByteStream;

    public void Dispose()
    {
        if (FileByteStream != null)
        {
            FileByteStream.Close();
            FileByteStream = null;
        }
    }
}

Client configuration:

<bindings>
  <basicHttpBinding>
    <binding name="FileTransferServicesBinding" sendTimeout="01:05:00"
        maxReceivedMessageSize="10067108864" messageEncoding="Mtom"
        transferMode="Streamed" />
  </basicHttpBinding>
</bindings>
<client>
  <endpoint address="http://localhost:11291/TransferService.svc/"
      binding="basicHttpBinding" bindingConfiguration="FileTransferServicesBinding"
      contract="TransferServiceReference.ITransferService" name="FileTransferService"
      kind="">
    <identity>
      <dns value="localhost" />
      <certificateReference storeName="My" storeLocation="LocalMachine"
          x509FindType="FindBySubjectDistinguishedName" />
    </identity>
  </endpoint>
</client>
<behaviors>
  <serviceBehaviors>
    <behavior>
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
  </serviceBehaviors>
</behaviors>

Client code:

ITransferService clientUpload = new TransferServiceClient();

string datetime = clientUpload.TestMethod();

var uploadRequestInfo = new RemoteFileInfo();

uploadRequestInfo.FileName = FileUpload1.FileName;
uploadRequestInfo.Length = FileUpload1.PostedFile.ContentLength;
uploadRequestInfo.FileByteStream = FileUpload1.PostedFile.InputStream;
clientUpload.UploadFile(uploadRequestInfo);

The call fails for both clientUpload.TestMethod() and clientUpload.UploadFile(uploadRequestInfo). With buffered mode clientUpload.TestMethod() is invoked so the issue is with the configuration in the streaming mode.

I'd be grateful to find any help on this matter. Thanks.
