The Visual Studio Gallery is the best place to find tools, controls, extensions and templates to help make your life as a developer easier and more productive.
These extensions are almost always language/platform agnostic and just make Visual Studio better and/or easier to work in. A lot of these owned by Microsoft, Microsoft DevLabs, or Microsoft employees or individuals. These extensions generally fall into language specific or technology specific extensions. That really means they may only b useful to you at certain times.
