I can't turn off Request Validation for an ASP.NET MVC Controller

Question

I am trying to turn off Request Validation for all action methods in a controller by doing this:

[ValidateInput(false)]
public class MyController : Controller         


        

Answer 1

Pro ASP.NET MVC Framework (p466) says the following is supposed to work:

public class MyController : Controller 
{
     public MyController() {
        ValidateRequest = false;
     }
}
