C# &引用；未找到默认端点"；启动WCF客户端时

我有一个代表WCF主机的Windows服务和一个代表WCF客户端的WPF客户端应用程序。 通信应该是双工的，所以我使用了WSDualHttpBinding。 首先，我安装并启动服务，打开WCF连接，然后启动WPF应用程序，出现以下错误（我翻译了它）： 找不到合同的默认终结点 \服务模型客户端配置部分中的“WCFCloudManagerFolderWatcherService.Interfaces.IFilesDuplex\” 指。这可能是由以下原因造成的：出于目的，未找到任何配置文件 或者在client元素中找不到与此约定对应的端点元素

合同： 如有必要，合同：

[ServiceContract(Namespace = "http://Microsoft.ServiceModel.Samples", SessionMode = SessionMode.Required,
            CallbackContract = typeof(IFilesDuplexCallback))]
public interface IFilesDuplex
{
    [OperationContract(IsOneWay = true)]
    void Update();
}

IFilesDuplexCallback：

interface IFilesDuplexCallback
{
    [OperationContract(IsOneWay = true)]
    void Equals(string[] result);
}

客户端 回调处理程序：

class CallbackHandler : IFilesDuplexCallback
{
    public event Action<string[]> ReceivedList = delegate { };

    public void Equals(string[] result)
    {
        this.ReceivedList(result);
    }
}

服务器端（Windows服务） FileProtocoll类（服务器代码）

OnStop方法中的代码（在线程中）：

App.config：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/>     
    </startup>
  <system.serviceModel>
    <services >
      <service behaviorConfiguration="ServiceBehavior"
   name="WCFCloudManagerFolderWatcherService.Communication.FileProtocoll">
        <endpoint address="http://localhost:8899/CloudManager /CommunicationChannel1"
        binding="wsDualHttpBinding"     contract="WCFCloudManagerFolderWatcherService.Interfaces.IFilesDuplex">
          <identity>
            <dns value="localhost"/>
          </identity>
        </endpoint>
        <endpoint address="mex"
        binding="mexHttpBinding" contract="IMetadataExchange"/>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior">
          <serviceMetadata httpGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true "/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
</configuration>

我终于拿到了。 必须对我的客户端app.config进行一些更改，并关闭安全性

app.config（客户端）：

<!-- WCF Client information-->
<system.serviceModel>
<bindings>
  <wsDualHttpBinding>
    <binding name="WSDualHttpBinding_IFilesDuplex">
      <security mode="None"/>
    </binding>
  </wsDualHttpBinding>
</bindings>
<client>
  <endpoint
    address="http://localhost:8899/CloudManager/CommunicationChannel1"
    binding="wsDualHttpBinding"
    bindingConfiguration="WSDualHttpBinding_IFilesDuplex"
        contract="WCFCloudManagerFolderWatcherService.Interfaces.IFilesDuplex"
    name="WSDualHttpBinding_IFilesDuplex">
    <identity>
      <userPrincipalName value="localhost"/>
    </identity>
  </endpoint>
</client>

在服务器端的app.config中，我还需要设置帽子

<security mode="None"/>

现在连接正常。

和其他许多人都在处理这个问题。这通常是一个配置问题。

// Step 1 Create a URI to serve as the base address.
        Uri baseAddress = new Uri("http://localhost:8899/CloudManager/CommunicationChannel1");

        // Step 2 Create a ServiceHost instance
        if (selfHost != null)
        {
            selfHost.Close();
        }

        selfHost = new ServiceHost(typeof(FileProtocoll), baseAddress);

        try
        {
            // Step 5 Start the service.
            selfHost.Open();



        }
        catch (CommunicationException ce)
        {
             selfHost.Abort();
        }

if (selfHost != null)
        {
            if (selfHost.State != CommunicationState.Closed)
            { 
                selfHost.Close();
            }

            selfHost = null;
        }
