I got the request to make an entry on what kind of tools I use on a day to day basis while developing ASP.NET 2.0 Applications. The main tool I use is of course VS2005 with Team foundation server as the source control system. I separated the other tools depending on the environment they are used from.

Plug-ins for Visual Studio
Simian - Similarity Analyser	This tool makes it possible to detect duplicate code within a file, project or solution.
Team Build Sidekick	Allows to Check the team build in and out.
Plug ins for Internet Explorer
Fiddler	Allows to intercept the HTTP Traffic. Very useful to see the content of the files that are requested.
Developer toolbar	Allows to check the properties of the elements that are rendered in the browser.
Tools for the build
Cruise Control.Net	Allows the continues integration of .NET applications
TFS CruiseControl.Net plugin	The Plug in to use Team Foundation Server with Cruise Control
Tools for the Team Foundation Server
Teamplain	Web UI for the Team Foundation Server
Custom developed RRSfeed	This tool allows to subscribe to all the work items, your work items, the team builds, the check ins via a news reader tool.

There will be more information on the ASP.NET developer tools later.
