I’m a bit behind the curve on this one, but I’m now developing with the 30 day trial of ReSharper by JetBrains. I haven’t even tried all of the features. There are keyboard chords and hidden features I need to learn. The obvious ones are code-formatting and general helping you out. It will close your braces, parens, quotes, etc. It color codes different types of members.
As I get more into Agile development methodologies, I’m trying to leverage more tools in order to be more productive.
