Is there a tool available that can scan a C# or VB.NET project and automatically remove all unused local variables?

You can use ReSharper. It will mark all unused variables and allow you to remove them.
Unused local variable: '<localvariablename>'A local variable in a procedure is declared but never used. One possibility is that there is a spelling mistake among the local variables in the procedure.
You can delete all unused variables of a selected area: Open the source code editor of the development object. Select the code where you want to delete the unused variables. From the context menu, choose Source > Delete Unused Variables (Selection) (Ctrl + Shift U).
Ahem: FxCop and ReSharper are nice and all, but the compiler will happily ignore unused variables and never even declare them in compiled code if you enable the optimize option.
