在WCF端点中无法获取元数据错误

Question

我正在为WCF在VS 2012中进行测试。它具有自定义的Http绑定，并在端点中使用。但它给出了一个错误，它在wcfclient.exe

中测试时找不到元数据以下是我在web.config文件中所做的自定义代码。

<bindings> 
     <basicHttpBinding> 
     <binding name="MaxHttp" allowCookies="true" 
       maxReceivedMessageSize="20000000" 
       maxBufferSize="20000000" 
       maxBufferPoolSize="20000000"> 
      <readerQuotas maxDepth="32" 
       maxArrayLength="200000000" 
       maxStringContentLength="200000000"/> 

     </binding> 
     </basicHttpBinding> 
     <!----> 
    </bindings> 
    <services> 
     <service name="AdventureW.Service.Database.AwService"> 
     <endpoint address="http://localhost:49551" binding="basicHttpBinding" bindingConfiguration="MaxHttp" contract="AdventureW.Service.Database.IWsService"/> 
     </service> 
    </services>

一个MEX（元数据交换）端点添加到您的服务，添加行为，允许对HTTP获取和更新服务，使用行为：

<system.serviceModel> 
    <bindings> 
     ... 
    </bindings> 

    <services>  
     <service name="AdventureW.Service.Database.AwService" behaviorConfiguration="ServiceBehavior">  
     <endpoint address="http://localhost:49551" binding="basicHttpBinding" bindingConfiguration="MaxHttp" contract="AdventureW.Service.Database.IWsService"/> 
     <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
     </service>  
    </services> 

    <behaviors> 
     <serviceBehaviors> 
     <behavior name="ServiceBehavior"> 
      <serviceMetadata httpGetEnabled="True" /> 
     </behavior> 
     </serviceBehaviors> 
    </behaviors> 
    </system.serviceModel>
