【问题描述】：

经过 3 天的永无止境的搜索，我发布了这个。请帮忙。以下是我拥有的配置文件。只指定了一个端点，但它说端点存在冲突。请帮我纠正这个冲突。

System.InvalidOperationException：绑定实例已经关联到监听 URI 'http://dd.myserver.net/MyWebService/MyService'。如果两个端点想要要共享相同的 ListenUri，它们还必须共享相同的绑定对象实例。指定了两个冲突的端点在 AddServiceEndpoint() 调用中、在配置文件中或以下组合中 AddServiceEndpoint() 和配置。

【解决方案1】：

最后我解决了一个人给出的错误 [https://stackoverflow.com/questions/12643113/wcf-conflicting-endpoints-after-net-4-5-installation/39394010]

我刚刚去掉了里面的安全标签

之前

 <webHttpBinding>
        <binding maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647">
          <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647"/>
          <security mode="None">
          </security>
        </binding>
      </webHttpBinding>

之后

<webHttpBinding>
        <binding maxReceivedMessageSize="2147483647" maxBufferPoolSize="2147483647" maxBufferSize="2147483647">
          <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647"/>
         </binding>
      </webHttpBinding>

这个小东西花了我 3 天的时间搜索。感谢stackoverflow。
