Not able to access WCF service (ESB.TranformService.WCF) from client application

Question

While trying to add service reference (http://<ServerName>/ESB.TransformServices.WCF/TransformationService.svc) from C# console application......... we are getting error given below:

Server Error in '/ESB.TransformServices.WCF' Application.

Hi Tukai,

This is a WCF error. Verify that you have a web.config file in the %ESB 2.0 Install Dir%\Web\ESB.TransformationServices.WCF and that it contains the following:

<system.serviceModel>
  <services>
   <!-- Before deployment, you should remove the returnFaults behavior configuration to avoid disclosing information in exception messages -->
   <service name="TransformationService" behaviorConfiguration="returnFaults">
    <endpoint contract="Microsoft.Practices.ESB.TransformServices.ServiceContracts.ITransformationService" binding="wsHttpBinding"/>
   </service>
  </services>
  <behaviors>
   <serviceBehaviors>
    <behavior name="returnFaults">
     <serviceMetadata httpGetEnabled="true"/>
     <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
   </serviceBehaviors>
  </behaviors>
 </system.serviceModel>
