Productive Dev Tools

This page contains tools that I find productive. I use these tools regularly either on the job or while doing my own development projects.

IntelliJ - http://www.jetbrains.com/idea/

A lightweight (comparatively), simple to use IDE. It supports several open source languages. It has free and premium versions.

dotCover - http://www.jetbrains.com/dotcover/

I use this to get code coverage of unit tests and execute unit tests when using nUnit with Visual Studio. Don't use this if you can use MS Test unit testing.
