Mvc Custom Error Page Not Working

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 mvc 404 error handling 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 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?

search for advice you will find 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 http://stackoverflow.com/questions/553922/custom-asp-net-mvc-404-error-page 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 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 https://dusted.codes/demystifying-aspnet-mvc-5-error-pages-and-error-logging 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, IHttpHandler ASP.NET itself is a larger framework to process incoming requests. Even though it could handle incoming requests from different sources, it is almost exclusively used with IIS. It can be extended with HttpModules and HttpHandlers. HttpModules are plugged into the pipeline to process a request at any point of the ASP.NET life cycle. A HttpHandler is responsible for producing a response/output for a request. IIS (Microsoft's web server technology) will create an incoming request for ASP.NET, which subsequently will start processing the request and eventually initialize th

MVC Routing, IIS, SEO, and Custom Errors – Oh My! Jul 21, 2015 Michael K. Campbell EMAIL Tweet Comments 0 Advertisement For all of its amazing strengths, it’s surprising how tedious it can be to get ASP.NET MVC applications to properly handle custom errors – especially if SEO is a concern. Part of this sadly stems from the fact that ASP.NET applications sometimes end up being subordinate to IIS in terms of error handling. But part of the problem also stems from the MVC routing problem itself. In this post I’ll outline some goals or expectations for error handling, cover some reasons why achieving these goals can sometimes be such a pain with MVC applications, provide some examples of how to get this working, and share a number of links to some great resources that shed additional light on the subject. Caller Beware, Caller Confuse, Caller Inform Handling HTTP errors should, ideally, conform to the age old development mantra that dictates that there are effectively three different ways to handle exceptions when they arise. Either you can do nothing and just let things ‘explode’ – potentially leaving things in an unstable state (i.e., Caller Beware), or, ideally, you’ll handle the error and inform the caller (be it an actual user sitting in front of a browser – or a bot) of the problem and some options to try and remedy the situation as per Caller Inform. Then, anything that falls between those two approaches amounts to Caller Confuse – and usually results from developers ‘bungling’ the error handling routine to some degree or another and making things possibly better or possibly worse than Caller Beware. Out of the box, I’d argue that ASP.NET and IIS both default more or less to Caller Beware – at least when SEO is a consideration and where typical end users are concerned – as ASP.NET’s Yellow Screen of Death (YSOD) and IIS’s
