I guess everyone has a list like this, so here is what I’m packing in my VS2010 lunchbox:

Extensions

Productivity Tools

VSCommands 2010 - Install, read about it, then realize why you need this!

Productivity Power Tools -

Power Commands for Visual Studio 2010 -

VS10x Comments Extender -

VS10x Method Block Highlighter -

Environments

Visual Studio 2010 SharePoint Power Tools – A must for SP2010 nerds

WCF REST Service Templates 40(CS) - If you do ANY web and REST services, you will want to get this.

Source Control

MercurialToolbar - Mercurial (hg)

Git Source Control Provider – GitHub etc.

AnkhSVN – Good Old SourceForge makes me have this, but thats ok!

Add-ons

WSPBuilder – Another SharePoint must-have

ReSharper – I cannot even begin to explain how important this is. Buy it. Did you get that? Buy it! And this is from a guy that refuses to buy anything.

TestDriven.NET -
