Fiddler is a simply wonderful tool when it comes to debugging your Silverlight applications. It really gives you a great idea as to what data is being passed to and from your Silverlight apps, and arms you with the tools necessary to find those small glitches that plague programmers.
I recently started using WCF RIA Services in Silverlight to build applications, and noticed that I was not able to read the data from my WCF service (I wanted to find out if I was getting too many records back from a database query).
I did some searching, and found that Samuel Jack has developed a plugin for Fiddler which allows you to view this data. Installation was easy – download the ZIP file, copy the .dll into the Fiddler > Inspectors directory, and away you go!
To ensure that the plugin allows you to get the data from your localhost server, just make sure to add a “.” after the word localhost when trying to capture the data in Fiddler:

Thanks Samuel! You hard work is much appreciated.
