当我调用WCF服务引用（net.tcp：// localhost：6256 / CalculatorService / mex）时，我收到此错误：
CalculatorServiceReference.AnswerResultClient client = new CalculatorServiceReference.AnswerResultClient("NetTcpBinding_IAnswerResult");
rtn = client.ServiceUpdate(org_int, sData); // ERROR HERE
client.Close();
在服务器中：
public interface IAnswerResult
{
[OperationContract]
bool ServiceUpdate(string org_int, string delimitedString);
}
public bool ServiceUpdate(string org_int, string delimitedString)
{
...
}
我有一个相同的服务器和服务，工作正常，我似乎找不到任何区别。错误立即发生，因此它似乎不是超时问题。
我尝试了跟踪查看器，但没有看到任何不在这里的东西。我甚至不确定我还能发布什么来帮助理解正在发生的事情。任何方向将不胜感激。

好吧，我做了另一个跟踪，发现有很多引用超时。这是否意味着什么新东西？

尝试为绑定配置“receiveTimeout”属性。
<system.serviceModel>
<bindings>
<wsHttpBinding>
<binding name="someBinding" receiveTimeout ="00:10:00">
...
</binding>
</bindings>
</system.serviceModel>
另请参阅Binding类的“closeTimeout”，“sendTimeout”和“openTimeout”属性。
您是否检查过该机器上的端口是否已打开？或者它可能被另一个进程使用？
您可以尝试在命令行界面中键入“netstat”以查看正在使用的端口。

Windows Service Pack更新包括环回检查安全功能，旨在帮助防止对计算机的反射攻击。因此，如果您使用的FQDN或自定义主机标头与本地计算机名称不匹配，则身份验证将失败。
所以，我所做的只是将WCF链接从localhost更改为计算机的名称，它工作了!!
