我有一个示例web应用程序，它使用带有web.config的wcf服务。

<system.serviceModel>
  <bindings>
  <wsHttpBinding>
    <binding name="TheBindingConfig">
      <security mode="None" >
         <transport clientCredentialType="None" />
    <message establishSecurityContext="false" />    
    </security>
    </binding>
  </wsHttpBinding>
</bindings>   
    <client>
      <endpoint address="http://localhost/myservice/Service.svc"
        binding="wsHttpBinding" bindingConfiguration="TheBindingConfig"
        contract="myservice.IService" name="WSHttpBinding_IService">
        <identity>
          <dns value="localhost" />
        </identity>
      </endpoint>
    </client>
  </system.serviceModel>

wcf服务配置文件如下

<system.serviceModel>
        <services>
            <service name="myservice.Service" behaviorConfiguration="ServiceBehavior">
                <!-- Service Endpoints -->
                <endpoint address="" binding="wsHttpBinding" contract="myservice.IService">
                    <!-- 
              Upon deployment, the following identity element should be removed or replaced to reflect the 
              identity under which the deployed service runs.  If removed, WCF will infer an appropriate identity 
              automatically.
          -->
                    <identity>
                        <dns value="localhost" />
                    </identity>
                </endpoint>
                <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior name="ServiceBehavior">
                    <!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
                    <serviceMetadata httpGetEnabled="true" />
                    <!-- To receive exception details in faults for debugging purposes, set the value below to true.  Set to false before deployment to avoid disclosing exception information -->
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
    </system.serviceModel>

请注意，服务是使用名称空间“myservice”创建的
我是错误响应为

The message could not be processed. This is most likely because the action 'http://tempuri.org/IService/GetUserDetails' is incorrect or because the message contains an invalid or expired security context token or because there is a mismatch between bindings. The security context token would be invalid if the service aborted the channel due to inactivity. To prevent the service from aborting idle sessions prematurely increase the Receive timeout on the service endpoint's binding.

注意：服务按预期正常运行
我猜上面的webconfig文件之间存在Map问题
等待您宝贵的回应和建议
