Mvc 5 Handle 404
error page when someone types in a URL that doesn't invoke a valid action or controller in ASP.NET MVC. Instead of it displaying the generic Resource Not Found ASP.NET error... I don't want to use the web config to handle this. Is there any kind of routing magic I can do to catch any invalid URLs? Update: I tried the answer given... however I still get the ugly resource not found message. Another update
Aspnet Mvc Nuget
OK. Apparently something changed in RC1.. I've even tried specifically trapping 404 on an HttpException and it still just gives me the resource not found page. I've even used mvcContrib's resource's feature and nothing. Same problem... Any ideas anyone?

Just do this..." But I'd suggest that if there is nothing stopping you from using the web.config approach and it satisfies your needs, it is a standard and elegant approach. Any feedback on that approach is appreciated, as there very well could be some issue with it that I don't know about.

integration, API and much more. Custom error pages and global error logging are two elementary and yet aspnet mvc 4 very confusing topics in ASP.NET MVC 5. There are numerous ways of implementing error pages in ASP.NET MVC 5 and when you search for advice you will find http://stackoverflow.com/questions/553922/custom-asp-net-mvc-404-error-page a dozen different StackOverflow threads, each suggesting a different implementation. Overview What is the goal? Typically good error handling consists of: Human friendly error pages Custom error page per error code (e.g.: 404, 403, 500, etc.) Preserving the HTTP error code in the response to avoid search engine indexing Global error logging for unhandled exceptions Error pages https://dusted.codes/demystifying-aspnet-mvc-5-error-pages-and-error-logging and logging in ASP.NET MVC 5 There are many ways of implementing error handling in ASP.NET MVC 5. Usually you will find solutions which involve at least one or a combination of these methods: HandleErrorAttribute Controller.OnException Method Application_Error event customErrors element in web.config httpErrors element in web.config Custom HttpModule All these methods have a historical reason and a justifyable use case. There is no golden solution which works for every application. It is good to know the differences in order to better understand which one is applied best. Before going through each method in more detail I would like to explain some basic fundamentals which will hopefully help in understanding the topic a lot easier. ASP.NET MVC Fundamentals The MVC framework is only a HttpHandler plugged into the ASP.NET pipeline. The easiest way to illustrate this is by opening the Global.asax.cs: public class MvcApplication : System.Web.HttpApplication Navigating to the implementation of HttpApplication will reveal the underlying IHttpHandler and IHttpAsyncHandler interfaces: public class HttpApplication : IComponent, IDisposable, IHttpAsyncHandler, IHttpHand
you're not alone. It's surprisingly difficult to do this correctly, not helped by the fact that some errors are handled http://benfoster.io/blog/aspnet-mvc-custom-error-pages by ASP.NET and others by IIS. Ideally (and I expect such is the case with some other frameworks/servers) we would just configure our custom error pages in one place http://www.devcurry.com/2012/06/aspnet-mvc-handling-exceptions-and-404.html and it would just work, no matter how/where the error was raised. Something like:
404 Page Not Found
I created a new ASP.NET MVC 5 application using the standard template in Visual Studio. If I run the site and try to navigate to a resource that does not exist e.g. /foo/bar, I'll get the standard ASP.NET 404 page with the following information: Server Error in '/' Application. The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /foo/bar Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.33440 Not exactly friendly, is it? In this case the error was raised by ASP.NET MVC because it could not find a matching controllerthe default HandleError Attribute in MVC. In this article, we will see how we can use the HandleError attribute to quickly put together an exception handling mechanism that helps hide the ‘dark' underbelly of your application but helps you debug with the same configuration. We will also look at a solution to handle 404 errors gracefully. Overall we try to achieve the following on IIS 7+ Goal 1 - Use MVCs HandleError action filter to take care of Unhandled/Unexpected errors Goal 2- See only user friendly messages at Runtime Goal 3 - See exception stack traces at debug time Goal 4- Manage 404 error with a proper error message Goal 5 - Keep a 404 Response status The HandleError Attribute The HandleError attribute helps mark controller classes for ‘Unhandled Error' exceptions. The HandleErrorAttribute() attribute filter will pipe the Unhandled exceptions to this attribute filter enabling you to take appropriate exception. The attribute filter is put in place by the default MVC template in the Global.asax (or for MVC4 in the App_Start\FilterConfig.cs) by adding the Action filter as follows: public static void RegisterGlobalFilters(GlobalFilterCollection filters) { filters.Add(new HandleErrorAttribute()); } By default, if you turn on CustomErrors, the behavior of the HandleErrorAttribute is to redirect you to the default Error page. Setting up the Custom Errors page Setup of the Custom Errors page is easy. We simply turn on the CustomErrors in the web.config. To Test the setting we throw an exception in the ‘About' action method of the Home Controller public ActionResult About() { ViewBag.Message = "Your app description page."; throw new ApplicationException("Testing default ErrorHandler attribute"); //return View(); } Now when we run the application and click on ‘About' we see the following This is the default output from Errors.csht
