Question

尝试在localhost中启动Web服务时，我一直收到此错误：

WCF服务主机找不到任何服务元数据

这是应用程序配置文件：

     <?xml version="1.0" encoding="utf-8" ?>
    <configuration>
      <appSettings>
    <add key="SrvName" value="..."/>
    <add key="DbName" value="..."/>
    <add key="DbId" value=".."/>
    <add key="DbPw" value=".."/>
    <add key="userId" value=".."/>
    <add key="userPw" value=".."/>
    <add key="code_rep" value=".."/>
    <add key="tex_rep" value=""/>
    <add key="F_LOG" value="logCla.txt"/>
  </appSettings>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="simplecalculmexcomport">
          <serviceDebug includeExceptionDetailInFaults="true" />
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="simplecalculmexcomport" name="WcfsaveRepES.service">
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration=""
            name="simplecalculhttpservice" contract="WcfsaveRepES.Iservice" />
        <endpoint address="mex" binding="mexHttpBinding" bindingConfiguration=""
            name="simplecalculmexpservice" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8081/" />
          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>
</configuration>

有解决方案吗？谢谢

我通过将配置添加到我的Console文件中，在Appconfig应用程序中对其进行了测试。它正常工作。
服务器端（Console应用程序，命名空间为ConsoleApp4）。

  class Program
    {
        static void Main(string[] args)
        {
            ServiceHost host = new ServiceHost(typeof(Service1));
            host.Open();
            Console.WriteLine(host.Description.Endpoints[0].Address);

            Console.ReadLine();
            host.Close();
        }
    }
    [ServiceContract(Namespace ="ABCD")]

    public interface IService1
    {

        [OperationContract]

        string GetData(int value);

    }
    public class Service1 : IService1
    {
        public string GetData(int value)
        {
            return string.Format("You entered: {0}", value);
        }
    }

App.config

  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior name="simplecalculmexcomport">
          <serviceDebug includeExceptionDetailInFaults="true" />
          <serviceMetadata httpGetEnabled="true" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <services>
      <service behaviorConfiguration="simplecalculmexcomport" name="ConsoleApp4.Service1">
        <endpoint address="" binding="basicHttpBinding" bindingConfiguration=""
            name="simplecalculhttpservice" contract="ConsoleApp4.IService1" />
        <endpoint address="mex" binding="mexHttpBinding" bindingConfiguration=""
            name="simplecalculmexpservice" contract="IMetadataExchange" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:9099/" />
          </baseAddresses>
        </host>
      </service>
    </services>
  </system.serviceModel>

该服务可以正常运行。您的项目类型是什么？在互联网上搜索了相关的错误之后，该错误似乎主要涉及合格的名称空间问题（服务的Name属性，端点部分的Contract属性）。请参考以下主题。

Trying to self-host, I get error - wcf service host cannot find any service metadata .. please check if metadata is enabled
