内容类型为 text/html;响应消息的 charset=utf-8 与关联的内容类型不匹配 （text/xml; charset=utf-8）

问：

我在 IIS 和 Visual Studio - asp 项目中使用， 我收到此错误：

System.ServiceModel.ProtocolException HResult=0x80131501 Message=内容类型为 text/html;响应消息的 charset=utf-8 与关联的内容类型 （text/xml; charset=utf-8） 不匹配。如果使用的是自定义编码器，请确保正确实现 IsContentTypeSupported 服务操作。响应的前 1024 个字节是：...

这是我的web.config：

<basicHttpBinding>
  <binding name="BasicHttpBinding_ICRMAppsDataProvider"  maxReceivedMessageSize="2147483646" />
      <binding name="DataServiceSoap" />
      <binding name="BasicHttpBinding_IService1" closeTimeout="00:05:00" 
               openTimeout="00:05:00" receiveTimeout="00:10:00" sendTimeout="00:25:00"
               allowCookies="false" bypassProxyOnLocal="false" maxBufferPoolSize="2147483646"
               maxReceivedMessageSize="2147483646" useDefaultWebProxy="true" textEncoding="utf-8">
          <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Windows" />
          </security>
  </binding>
</basicHttpBinding>

和这个服务器 web.config：

  <services>
  <service behaviorConfiguration="ManagementServiceBehaviour" name="AService.Service1">
    <endpoint address="" binding="basicHttpBinding" bindingConfiguration="basicHttpBinding" contract="AService.IService1" />
  </service>

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

</services>

    </binding>

    </binding>
  </webHttpBinding>
