Remove unused namespaces across a whole project or solution at once

Question

I know you can do it file by file.

Is there any way to do this in one step for all files in a project?

Answer 1

For Visual Studio 2010 you can download the "Remove and Sort Using"extension from the Visual Studio Gallery.
