Webeando, encotre esta excelente nota, aunque viejita, de los 10 tools que todo desarrollador .net debe tener. Esta es la lista:
* 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
