我們流使用WCF回調的數據。 WCF託管在IIS中（默認設置，只是將net.tcp添加到協議中）。WCF在安全模式下沒有給出的net.tcp例外
我們正試圖在WCF禁用安全性，所以我設置安全模式爲「無」，在客戶端和服務器上，但我得到了以下的CommunicationException：
套接字連接被中止。這可能是由於處理您的消息的錯誤 或遠程主機的 接收超時或基礎網絡資源問題所致。本地套接字 超時時間爲'00：00：59.8439844'。
我已經把關於服務跟蹤和TraceViewer給了我下面的異常（System.ServiceModel.ProtocolException）：
流安全要求在 http://www.w3.org/2005/08/addressing/anonymous，但沒有安全 上下文經過談判。這很可能是由遠程端點 從其綁定中丟失了StreamSecurityBindingElement引起的。
客戶端的Program.cs：
using System;
using System.ServiceModel;
using WcfClient.ServiceReference1;
class Program {
static void Main() {
Callback callback = new Callback();
InstanceContext context = new InstanceContext(callback);
Service1Client service1Client = new Service1Client(context,
"NetTcpBinding_IService1");
service1Client.GetData(0);
Console.Read();
service1Client.Stop();
}
}
internal class Callback : IService1Callback {
public void StreamSignalData(int[] result) {
foreach (int i in result) {
Console.WriteLine(DateTime.Now.ToString("dd.MM.yyyy HH:mm:ss.fff") +
": " + i);
}
}
}

任何想法，這可能是？ 谷歌上的大部分命中都表示客戶端和服務器上的配置應該是相同的（即安全性爲無），但我似乎無法找到該錯誤。 谷歌搜索StreamSecurityBindingElement想出了沒有好explenations ...
哪一方（客戶端/服務）給你日誌中的錯誤？ – 2013-05-08 18:45:55
@PetarVučetin服務。 – ahoibakk 2013-05-09 06:17:12
@PetarVučetin我試圖在客戶端上進行跟蹤，但是除了已經拋出的異常外，它沒有給出任何其他信息。 – ahoibakk 2013-05-12 10:34:32
