How to make custom error pages work in ASP.NET MVC 4

Question

I want a custom error page shown for 500, 404 and 403. Here\'s what I have done:

1. Enabled custom errors in the web.config as follows:

Answer 1

My current setup (on MVC3, but I think it still applies) relies on having an ErrorController, so I use:

And the controller contains the following:

public class ErrorController : Controller
{
    public ViewResult Index()
    {
        return View("Error");
    }
    public ViewResult NotFound()
    {
        Response.StatusCode = 404;  //you may want to set this to 200
        return View("NotFound");
    }
}

And the views just the way you implement them. I tend to add a bit of logic though, to show the stack trace and error information if the application is in debug mode. So Error.cshtml looks something like this:

@model System.Web.Mvc.HandleErrorInfo
@{
    Layout = "_Layout.cshtml";
    ViewBag.Title = "Error";
}

    Error


    

        An unexpected error has occurred. Please contact the system administrator.
    
    @if (Model != null && HttpContext.Current.IsDebuggingEnabled)
    {
        

            

                Exception: @Model.Exception.Message

                Controller: @Model.ControllerName

                Action: @Model.ActionName
            
            

                
                    @Model.Exception.StackTrace
                
            
        
    }
