I am attempting to debug a (RESTful) WCF app using Fiddler. I run my project via VS IDE - which launches my app in the ASP.NET Development Server aka Cassini. I then launch Fiddler and in the Request Builder tab enter the following: "http://localhost:1066/GeneralService/sections/summary" with GET as the http method.
Fiddler responds with "[Fiddler] Connection to localhost failed.
Exception Text: No connection could be made because the target machine actively refused it ::1:1066 "
Is there some way for me to debug an app running on Cassini?
Thanks, Steve
Change the url to http://ipv4.fiddler:1066/GeneralService/sections/summary to enable fiddler to listen on localhost
One neat trick is just to add a period(.) after the word localhost. No other config neccesary.
You can use the integrated traffic monitor built into CassiniDev. It can be run stand-alone or as a direct drop-in replacement for VS 2008/2010 development servers.
