WCF绑定不匹配

我的WCF绑定将不匹配。我正在使用下面的源代码

static class Utilities
{
    internal static MessageVersion MessageVersion
    {
        get { return MessageVersion.Soap12WSAddressing10; }
    }
}

public class LiveChatServiceHost : ServiceHost
{
    public LiveChatServiceHost(params System.Uri[] addresses)
    {
        base.InitializeDescription(typeof(LiveChatService), new UriSchemeKeyedCollection(addresses));
    }

    protected override void InitializeRuntime()
    {
        string pollTimeout = ConfigurationManager.AppSettings["PollTimeout"];
        string inactivityTimeout = ConfigurationManager.AppSettings["InactivityTimeout"];

        PollingDuplexBindingElement pdbe = new PollingDuplexBindingElement()
        {
            ServerPollTimeout = TimeSpan.Parse(pollTimeout),
            InactivityTimeout = TimeSpan.Parse(inactivityTimeout)
        };

        AddServiceEndpoint
        (
            typeof(ILiveChatService),
            new CustomBinding(pdbe,
                   new TextMessageEncodingBindingElement(Utilities.MessageVersion, System.Text.Encoding.UTF8),
                   new HttpTransportBindingElement()),
                   ""
        );

        base.InitializeRuntime();
    }
}

如果我看到WCF日志，那么

异常树：

System.ServiceModel.ProtocolException，System.ServiceModel， 版本=4.0.0.0，区域性=中性，PublicKeyToken=b77a5c561934e089

例外信息：

异常类型：System.ServiceModel.ProtocolException， System.ServiceModel，版本=4.0.0.0，区域性=中性， PublicKeyToken=b77a5c561934e089消息：内容类型 application/soap+msbin1已发送到一个服务，该服务需要 application/soap+xml；字符集=utf-8。客户端和服务绑定 可能不匹配。堆栈跟踪：

Web.Config

<system.serviceModel> 
   <behaviors> 
      <serviceBehaviors> 
         <behavior name=""> 
            <serviceMetadata httpGetEnabled="true" /> 
            <serviceDebug includeExceptionDetailInFaults="false" /> 
         </behavior> 
      </serviceBehaviors> 
   </behaviors> 
   <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> 
</system.serviceModel>

如何在帖子中显示配置？我无法添加web.config。此外，我没有客户端配置。我直接使用Wcf服务视图标记获取===
