Visual Studio 2010 Feature Builder Power Tool
A new power tool named Feature Builder for Visual Studio 2010 was just published on the Visual Studio gallery site.
This power tool helps you easily create rich Visual Studio extensions which you can share with others on the Visual Studio Gallery. These extensions can include tools (Visual Studio automation), code (your sample code or binaries you wish to share with others) and a map (a set of steps your users will want to follow to get the best experience with your extension). You can use this power tool to quickly package up sample code with custom menus, or take the time to create complete automated guidance experiences targeted toward a specific technology.
It comes in two flavors for VS Professional/Premium and Ultimate separately. Go check it out if you have the need to extend Visual Studio IDE functionality.
