Play The VS2010 Extension Manager
One of the big initiatives for Visual Studio 2010 was to incorporate the community directly into the IDE itself and the extension manager was created to achieve just that. This newcomer to VS allows the user to consume extensions posted to the Visual Studio Gallery right from within VS itself. It provides the ability to search and browse through the gallery's repository as well as manage the extensions you already have installed on your machine. We think it represents a big step forward in our hope to take the ecosystem to new heights. Enjoy!
