Unrecognized element 'extendedProtectionPolicy'.

When I am Trying To Add A Service.svc, Then I Got this Error  ConfigurationErrorsException was unhandled. Unrecognized element 'extendedProtectionPolicy'.

It May Also Come At The Time Of Building The Application Having WCF Service.

To Rectify This Error, Remove The 

<extendedProtectionPolicy policyEnforcement="Never"/> tag In The Web.Config File, Now The Application Runs successfully
