客户端 app.config 生成重复端点 [WCF]

Question

我有一个客户端，它使用对我的本地主机上的 NetTCPBinding 的服务引用来生成其 app.config。出于某种原因，当我在客户端上运行我的服务并更新服务引用时，app.config 文件会复制端点（增加名称）而不是替换当前文件。

如何阻止客户端 app.config 复制端点？

这是我的服务 app.config：

  <services>
    <service name="Embedded_DCC_Service.EmbeddedService" behaviorConfiguration="serviceBehavior">
      <endpoint
        name ="TCPEndPoint"
        binding="netTcpBinding"
        contract="Embedded_DCC_Service.IEmbeddedService"
        address="EmbeddedService"
        bindingConfiguration="EmbeddedService_Binding"
        />
      <endpoint
        name ="MetaDataTcpEndpoint"
        binding="mexTcpBinding"
        contract="IMetadataExchange"
        address="mex" 
        />
      <host>
        <baseAddresses>
          <add baseAddress="net.tcp://localhost:9292/"/>
        </baseAddresses>
      </host>
    </service>
  </services>

  <bindings>
    <netTcpBinding>
      <binding name="EmbeddedService_Binding" closeTimeout="infinite" openTimeout="infinite"
          receiveTimeout="infinite" sendTimeout="infinite" />
    </netTcpBinding>
  </bindings>

  <behaviors>
    <serviceBehaviors>
      <behavior name="serviceBehavior">
        <serviceMetadata httpGetEnabled="false"/>
      </behavior>
    </serviceBehaviors>
  </behaviors>

</system.serviceModel>

以及在客户端生成的 app.config（带有重复条目）：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <bindings>
      <netTcpBinding>
        <binding name="TCPEndPoint" closeTimeout="00:01:00" openTimeout="00:01:00"

看起来你的问题类似于this问题

它告诉这是 Visual Studio 2010 中的一个已知错误，并告诉检查这个link。

您也可以像这样尝试以编程方式绑定（您必须根据自己的选择进行更改）：

  BasicHttpBinding binding = new BasicHttpBinding(BasicHttpSecurityMode.None);
                binding.Name = "ActivationManagerSoap"; 
                binding.CloseTimeout = new TimeSpan(0, 5, 0); 
                binding.OpenTimeout = new TimeSpan(0, 5, 0); 
                binding.ReceiveTimeout = new TimeSpan(0, 5, 0); 
                binding.SendTimeout = new TimeSpan(0, 5, 0);
                binding.AllowCookies = false; 
                binding.BypassProxyOnLocal = false;
                binding.HostNameComparisonMode = HostNameComparisonMode.StrongWildcard; 
                binding.MaxBufferSize = 65536; binding.MaxBufferPoolSize = 524288;
                binding.MaxReceivedMessageSize = 65536;
                binding.MessageEncoding = WSMessageEncoding.Text;
                binding.TextEncoding = Encoding.UTF8;
                binding.TransferMode = TransferMode.Buffered;

                binding.UseDefaultWebProxy = true;
                XmlDictionaryReaderQuotas quotas = new XmlDictionaryReaderQuotas();
                quotas.MaxDepth = 32; 
                quotas.MaxStringContentLength = 8192; 
                quotas.MaxArrayLength = 16384; 
                quotas.MaxBytesPerRead = 4096;
                quotas.MaxNameTableCharCount = 16384;
                binding.ReaderQuotas = quotas;


                EndpointAddress addres = new EndpointAddress("http://xxxxxx/service");

                ActivationService.ActivationManagerSoapClient client = new ActivationService.ActivationManagerSoapClient(binding, addres);
