In the company I work for, there is a .NET application developed using WCF. There are 2 parts - 1. Application  server and 2. A thick client - Both installed on the same machine. The application server is IIS.

I would like to capture all SOAP calls make by the client to the application server. I tried Fiddler, but it is not capturing traffic to localhost at the moment. Any way to capture the WCF calls made to the localhost by the windows thick client?

I tried to remove "loopback" from Tools - Fiddler Options - Connections : "ByPass Fiddler for URL's that with", but unable to do this. 

If fiddler doesn't do this any other software that does this?

Hi,

The .NET Framework is hardcoded to bypass the proxy for localhost (a behavior which other clients can have disabled via the <-loopback> token you deleted prematurely).

To mitigate that problem, change the URL in the .NET client to use "localhost.fiddler" or the name of the machine instead.
