>This means that visual studio's 'find references' functionality doesn't work, and the project I'm working on has dozens of unused controllers I know it's an annoying extra step to learn and do, but when doing anything with refactoring controller actions (e.g. changing action names or required parameters), Ctrl+Shift+F is really your friend.
