我们正在使用回调与WCF进行数据流传输。 WCF托管在IIS中（默认设置，只是将net.tcp添加到协议中）

我们正在尝试禁用WCF上的安全性，因此我已将客户端和服务器上的安全模式设置为“无”，但我得到以下CommunicationException：

你知道这是什么吗？ 谷歌上的大多数点击都说客户端和服务器上的配置应该是相同的（即安全性为无），但我似乎找不到错误。
用谷歌搜索StreamSecurityBindingElement没有找到好的解释…

我无法复制您的问题，但我有相同的设置，几乎没有注意到什么：

在WCF Service1.svc.cs中创建名称空间

    namespace WcfService1
    {
        [ServiceContract(SessionMode = SessionMode.Required,
            CallbackContract = typeof (IStreamCallback),
            ProtectionLevel = ProtectionLevel.None)]
        public interface IService1
        {
        .....
        [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
        [CallbackBehavior(ConcurrencyMode = ConcurrencyMode.Multiple)]
        public 

    class Service1 : IService1
