WCFTestClient将无法连接到服务

Question

我收到错误：

Cannot obtain Metadata from http://localhost:8733/SolutionName/Service....
...There was an error downloading 'http://localhost:8733/SolutionName/Service'.
 The request failed with HTTP status 404: Not Found.

奇怪的是，我在今天早些时候通过WCFTestClient进行连接，然后对Service和IService文件进行了任何更改。

我有一个基本服务（自托管），用于测试使用以下配置的修改：

  <service name="SolutionName.Service">
    <endpoint address="" binding="basicHttpBinding" contract="SolutionName.IService">
      <identity>
        <dns value="localhost" />
      </identity>
    </endpoint>
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
    <host>
      <baseAddresses>
        <add baseAddress="http://localhost:8733/SolutionName/Service" />
      </baseAddresses>
    </host>
  </service>
  ....
  <serviceBehaviors>
    <behavior>
      <serviceMetadata httpGetEnabled="True" httpsGetEnabled="True"/>
      <serviceDebug includeExceptionDetailInFaults="False" />
    </behavior>
  </serviceBehaviors>

我有httpGetEnabled="True"喜欢它，但它仍然无法连接。我已经尝试删除输出目录中的所有内容，但问题仍然存在。

这是IService。新方法标有//NEW
