With everyone excited over VS 2008, I figure this might be a good time to give some link love to VS 2005 Addins.
Web Deployment Projects - Somewhere in the middle of "Publish Website" and "Web Application Projects" (introduced with SP1) sit Web Deployment Projects. Deployment projects are added to your existing website and appear as a separate project so you get to keep the easy-going website development model. Then when you are ready to deploy your site, you simply build the Deployment project, and a pre-compiled version of the site is created. You can also configure Debug and Release build that support different Web.config settings, making deployment a breeze.
Modeling PowerToys - This collection of Addins extends Class Designer and the Distributed Systems Designers in VS 2005. Perhaps one of the coolest features is the ability to export a Class Designer document as HTML or XML (in addition to PNG). Really handy for those who document their APIs.
WCF and WPF Extensions - Want to play with .Net 3.0 but don't have 15 GB of hard drive space to give over to a Virtual PC image of VS 2008 beta? These extensions add support to VS 2005 for WCF and WPF so you can begin developing .Net 3.0 apps without VS 2008. There is also support for Workflow (WF).
Spell Checker for VS 2005 - As programmers we have enough to learn already - who has time for learning a language that doesn't compile? This extension works with Word 2000 or higher to spell check comments, strings, and more.
