For Global Error Handling
All you have to do is change the customErrors mode="On" in web.config page
Error will be displayed through Error.cshtml resides in shared folder.

Make sure that Error.cshtml Layout is not null.
[It sould be something like: @{ Layout = "~/Views/Shared/_Layout.cshtml"; }
Or remove Layout=null code block]
A sample markup for Error.cshtml:-

@{ Layout = "~/Views/Shared/_Layout.cshtml"; } 

@model System.Web.Mvc.HandleErrorInfo




    


    

        Sorry, an error occurred while processing your request.
    
    
Controller Name: @Model.ControllerName
    
Action Name : @Model.ActionName
    
Message: @Model.Exception.Message

For Specific Error Handling
Add HandleError attribute to specific action in controller class. Provide 'View' and 'ExceptionType' for that specific error.
A sample NotImplemented Exception Handler:

public class MyController: Controller
    {
        [HandleError(View = "NotImplErrorView", ExceptionType=typeof(NotImplementedException))]
        public ActionResult Index()
        {
            throw new NotImplementedException("This method is not implemented.");
            return View();
        }
}
