WCF streaming issue

Question

I watched this topic: How to handle large file uploads through WCF?

I need to have a web service hosted by my provider, where I need to upload and download files. We are talking videos from 1Mb to 100Mb, hence the streaming approach.

I cannot make it work, I declared the interface:

[ServiceContract]
    public interface IFileTransferService
    {

        [OperationContract]
        void UploadFile(Stream stream);
    }

and everything is fine, I implement it as follows:

 public string FileName = "test";

        public void UploadFile(Stream stream)
        {
            try
            {
                FileStream outStream = File.Open(FileName, FileMode.Create, FileAccess.Write);
                const int bufferLength = 4096;
                byte[] buffer = new byte[bufferLength];
                int count = 0;
                while((count = stream.Read(buffer, 0, bufferLength)) > 0)
                {
                    //progress
                    outStream.Write(buffer, 0, count);
                }
                outStream.Close();
                stream.Close();
                //saved
            }
            catch(Exception ex)
            {
                throw new Exception("error: "+ex.Message);
            }
        }

Still not a problem, it was published on my web server in interweb. So far so good.

Now I will make a link to it and pass it the FileStream, but the argument is now a byte [] - why is this and how can I get it properly for streaming?

Edit My bindings look like this:

 <bindings>
      <basicHttpBinding>
        <binding name="StreamingFileTransferServicesBinding"
                 transferMode="StreamedRequest"
                 maxBufferSize="65536"
                 maxReceivedMessageSize="204003200"  />
      </basicHttpBinding>
    </bindings>

, , :

[OperationContract]
void UploadFile(Stream stream);

[OperationContract]
void UploadFile(FileDTO stream);

[MessageContract]
public class FileDTO : IDisposable
{
    [MessageBodyMember]
    public Stream FileStream { get; set; }

    [MessageHeader]
    public String FileLabel { get; set; }
}

:

client.UploadFile(fileLabel, fileStream);

String Stream.
