Question

I am building WCF pox and json rest service using WebScriptServiceHostFactory in framework 3.5 and i am sending the status code to client by throwing WebProtocolException. While doing so the exception is not well formatted and looks bad on the browser like below…..

Is there a way by which i format the exception on browser or suppress the exception in service and send only the status code to client.

Answer 1

This exception is due to multiple reasons. I was using the Factory along with the service configuration which was wrong. Also i had to make includeExceptionDetailInFaults = false and use custom behaviour and IErrorHandler to handle the WebProtocolException for rest.
