All errors should return proper Razor views, it would be very nice to have an ErrorController in front of the views. E.g. something like this: public class ErrorController : Controller { public ViewResult NotFound () { return mvc error handling View(); } public ViewResult Forbidden () { return View(); } public ViewResult Default () { var ex = ObtainExceptionFromSomewhere(); if(ex is MySpecialDomainException) return View("MySpecialDomainException", new ErrorModel { Exception = ex }); return View("GeneralError", new ErrorModel { Exception = ex }); } } Currently you find many different ways to do that on the www, some most probably outdated. Among those: Controller.OnException() Error filter customErrors element in web.config Handling in Global.asax's Application_Error Q1: What is the recommended way to fulfill our requirements with ASP.NET MVC 5? Also we want to catch errors occurring in the IIS host. Q2: To prevent that IIS has to handle any 404s we thought about adding a default route matching all possible URLs - is this recommendable? Better to register instead for IIS' 404s as well? Q3: Is it even possible to register an IIS error page which goes back to a controller, or is IIS capable of ASPX / static HTML only? c# asp.net-mvc error-handling asp.net-mvc-5 asp.net-mvc-5.1 share|improve this question edited Jul 26 at 6:09 Mukesh Ram 2,7373625 asked Feb 24 '14 at 16:46 D.R. 6,17272272 I'm curious..

ASP.NET MVC comes with built-in support for exception handling using a feature known as exception filters. We are going to learn two approaches here: one with overriding the onException method and another by defining the HandleError filters. Override OnException method This approach is used when we want to handle all the exceptions across the Action methods at the controller level. To understand this approach, create an MVC application (follow the steps covered in previous chapters). Now add a new Controller class and add the following code which overrides the onException method and explicitly throws an error in our Action method: Now let us create a common View named Error which will be shown to the user when any exception happens in the application. Inside the Views folder, create a new folder called Shared and add a new View named Error. Copy the following code inside the newly created Error.cshtml: If you try to run the application now, it will give the following result. The above code renders the Error View when any exception occurs in any of the action methods within this controller. The advantage of this approach is that multiple actions within the same controller can share this error handling logic. However, the disadvantage is that we cannot use the same error handling logic across multiple controllers. HandleError Attribute The HandleError Attribute is one of the action filters that we studied in Filters
