WCF配置netTCp，端点为空

Question

我收到以下错误

“地址属性 ChannelFactory.Endpoint 为空。这 ChannelFactory 的 Endpoint 必须有一个 指定的有效地址。”

，我不确定我做错了什么。有人知道它的原因是什么吗？下面是我项目的 App.config 服务器和客户端 感谢您的帮助，问候

Answer 1

您的配置存在一些问题。服务器通过 net.tcp 指定 DualService，但客户端使用 BasicHttpBinding 并且不指定地址。此外，您的客户端具有比您的服务公开更多端点的配置，并且 DualService 中的 mex 端点具有不正确的合同（应为 IMetadataExchange）。

只有 PhoneService 的客户端端点看起来正确。

Answer 2

一切正常，你是对的:)，再次感谢你，下面我放置了正确的配置，也许有一天它会对某人有所帮助，.. :D:D

在服务器端我已经更正了端点中的 IMetadataExchange ：

 <endpoint address="mex" binding="mexTcpBinding" contract="IMetadataExchange" /> 

并且我改变了 在客户端，

<behavior  name="NetTcpBehavior">
      <serviceMetadata/>
      <serviceThrottling maxConcurrentSessions="10000" />
    </behavior>

我删除了大多数与 DualService 相关的通用代码，并添加了

<endpoint name=""
              address="net.tcp://localhost:8731/Service/DualService/"
              binding="netTcpBinding"
              bindingConfiguration="DuplexBinding"
              contract="IDualService" />

绑定如下所示的位置：

<netTcpBinding>
        <binding name="DuplexBinding" sendTimeout="00:00:05" >
          <reliableSession enabled="true" />
          <security mode="None" />
        </binding>
      </netTcpBinding>
