Pimp my Visual Studio 2008 (developer tools)

I was kindly tagged by Gøran Hansen recently on his post about Visual Studio developer tools and add-ons, and so here's my list of tools. I'm going to make this more of a "tech tools I use in general" list rather than exclusively a Visual Studio or .NET list. It's a more accurate view of my development environment this way.

Visual Studio / C# / .NET

• Resharper. Code analysis and refactorings like no other tool. Visual Studio feels strange without it.
• LINQPad. For quick LINQ testing and experimenting.
• Snippet Compiler. Quickly run a bit of code, without creating a test project in Visual Studio.
• NUnit. Runs side by side with the code I'm currently working on.
• Reflector. For when I'm curious what's inside...
• Web Service Studio. Type in a web service URL. See the methods it exposes. Call them. See the results. Easy!

Other tools

• SQL Prompt. Intellisense in SQL Server!
• Firefox and it's many extensions: web development takes twice as long without Firebug. For picking colors, I use ColorZilla. Treat FTP like another webpage in a tab with FireFTP. For general web dev help: web developer toolbar. But the best, by far, is the delicious bookmarks extension.
• Delicious. A central place for my bookmarks.
• IE Tester. Test web sites in IE 5.5, IE 6, IE 7 and IE 8... all from within one window!
• UltraMon. Extend your windows start menu bar across both of your monitors like you know it should.
• Fiddler. HTTP debugger.

Heard about, want to use, but not had the chance yet...

• XUnit
• Subversion
• jQuery intellisense in the new Visual Studio
• WPF
• Silverlight
