Does anyone know of a tool to remove redundant using statements from classes, or a whole solution?

I'm using the Refactor! addin which has a "move type to separate file" smart tag, but it takes all the using clauses from the original class with it.

VisualStudio 2008 does this out of the box.

Simply right click in the code window -> Organise Usings -> Remove Unused Usings.

You can set up a shortcut key to do this, as explained here.

PowerCommands for Visual Studio upgrades the default VS.NET 2008 functionality of "Remove Usings" to an entire project or solution.

I use it all the time. It also has a lot of other useful features- check it out.

Best of all it is FREE.

+1 great tip. I've had PowerCommands installed for quite some time, but I never noticed that before.
@Joe- I've only recently noticed some of the other things it adds like "extract constant". Probably the most useful though is open containing folder- that's a real obvious feature that Visual Studio should have anyway.
My favourite PowerCommands feature is Collapse Projects - we work with huge solutions. BTW Open Containing Folder is a feature in VS 2010 :-)
I've got PowerCommands but didn't notice it there, or Joe's answer
@Joe- that's useful to know. Collapse projects is a real sanity saver with big solutions.

ReSharper does this.
