Useful developer tools (some for Visual Studio)

This article discusses ten must-have tools for developers. Many are for .NET and Visual Studio development, and they look pretty cool: 

NUnit to write unit tests

NDoc to create code documentation

NAnt to build your solutions

CodeSmith to generate code

FxCop to police your code

Snippet Compiler to compile small bits of code

Two different switcher tools, the ASP.NET Version Switcher and the Visual Studio .NET Project Converter

Regulator to build regular expressions

.NET Reflector to examine assemblies
