Hi ,
While i am adding a new wcf service to my existing application by choosing (Solution Explorer->Add new folder->gave name ,then on that folder i choose add new item->wcf service ->name->ok)
result: a interface and a implementation class. after doing some logic while i'm trying to run the wcf service its getting error .

Changed (Added)my web.config as below:

<services>
      <service name="Serviceforcgi.Service1" behaviorConfiguration="Serviceforcgi.Service1Behavior">
        <endpoint address="../Service1.svc" binding="webHttpBinding" contract="Serviceforcgi.IService1" behaviorConfiguration="webBehaviour" />
        <endpoint name="mexHttpBinding" address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
      </service> (for 1st service)
    
       <service name="Intranet.WCF_Service.CGI_Automated" behaviorConfiguration="Intranet.WCF_Service.CGI_AutomatedBehavior">
        <endpoint address="../WCF Service/CGI_Automated.svc" binding="webHttpBinding" contract="Intranet.WCF_Service.ICGI_Automated" behaviorConfiguration="webBehaviour" />
        <endpoint name="mexHttpBinding" address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
