I am reading an article regarding the ASP.NET MVC from SCOTTGU blog. In the article there is a code in which [ControllerAction] attribute is defined over the method. But when I do that I can getting compile time error - "The type or namespace name 'ControllerActionAttribute' could not be found (are you missing a using directive or an assembly reference?)"
But I have already included the following namespaces
Is there any thing I am missing?
