Unhandled WCF FaultException Errors
Have you ever created a WCF WebService with FaultExceptions and encountered those pesky “System.ServiceModel.FaultException`1” error messages when debugging your code? (If your answer is NO, skip reading this post altogether.) Rest assured this is not a fault in your code; it is a debugger issue. Instead of turning off all exception notifications like most articles online suggest, the easier way is to turn off flagging for that specific exception by going into Debug > Exceptions > System.ServiceModel > System.ServiceModel.FaultException’1 and unchecking the User-unhandled checkbox.
Simple as that.
