我知道这已被多次询问,并且多次回答,但是,所有提供的应该使用的样本似乎并不想今天为我工作.

当我尝试启动主机时,我不断收到以下错误:

"在服务TraceService实现的合同列表中找不到合同名称'IMetadataExchange'.将ServiceMetadataBehavior直接添加到配置文件或ServiceHost以支持此合同."

根据Microsoft的示例,我的服务托管在托管的Windows服务主机中:http://msdn.microsoft.com/en-us/library/ms733069%28v=vs.90%29.aspx

这是我的简单配置:

  <system.serviceModel>
    <services>
      <service name="Daff.Lae.Service.TraceService">
        <endpoint address="" binding="wsHttpBinding" name="TraceService" contract="Contracts.Service.ITraceService">
          <identity>
            <dns value="localhost" />
          </identity>
        </endpoint>
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8080/TraceService" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <serviceBehaviors>
        <behavior name="DefaultBehavior">
          <serviceDebug includeExceptionDetailInFaults="true"/>
          <serviceMetadata httpGetEnabled="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>

当然,如果删除此行,则没有错误时问题会变得更有趣:

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

任何帮助将非常非常感谢:)
