Fiddler not capturing while trying to debug WCF service

If you are building WCF service locally and using Fiddler to capture traffic for debugging, chances are you will not get any traffic recorded in Fiddler.

This might happen if you have mentioned "localhost" in service endpoint in Web.config. Once you have replaced localhost or 127.0.0.1 with <machinename>, you will get traffic recorded in Fiddler.
