    reqProps.Headers.Add("CustomHeader", "Test Value");
    reqProps.Headers.Add(HttpRequestHeader.UserAgent, "my user agent");

    try
    {
        messageToSend = Message.CreateMessage(MessageVersion.Soap11, "http://tempuri.org/IUntypedService/ProcessMessage", "Hello WCF");
    }
    catch (Exception e)
    {
