I'm trying to just display a friendly cshtml page whenever an exception mvc 5 redirect to error page is thrown so my UX is consistent - I don't want my users even knowing I'm on the .net stack from the UI, ever. I'm testing by navigating to localhost:2922/junkurl, - if the URL does not resolve, cannot be found, or otherwise generates an exception, I want to display a friendly rendered cshtml page. What I have in my web.config:

Page for 404 error is in the /ErrorPages/Error_404.cshtml In this file I have only HTML code and it works fine. But if I add some razor code it throws configuration error in browser. I add for example layout or some @Html.ActionLink(... This is error: Runtime Error Description: http://stackoverflow.com/questions/8858929/razor-code-in-cshtml-error-page-produce-error An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed. Details: To enable the details of this specific error message to be viewable on the local server machine, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "RemoteOnly". To enable the details to be viewable on remote machines, please set "mode" to "Off". This is how I produce 404: public ActionResult Search(string searchTerm) { if (city == null) { throw new HttpException(404, "Some description"); } else { return RedirectToAction("Index", "Home", new {... } } And when there is no razor code in error page it works and if not I get message from above. When I set in web config 'mode=Off' then I get error message: 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: /CityPage/Navigation/Sea
you're not alone. It's surprisingly difficult to do this correctly, not helped by the fact that some errors are handled by http://benfoster.io/blog/aspnet-mvc-custom-error-pages ASP.NET and others by IIS. Ideally (and I expect such is the https://dusted.codes/demystifying-aspnet-mvc-5-error-pages-and-error-logging case with some other frameworks/servers) we would just configure our custom error pages in one place 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 controller and/or action that matched the specifiedit as part of our official documentation for implementing custom error pages, we've decided to sponsor it.

Custom error pages and global error logging are two elementary and yet 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 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 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, IHttpHandler ASP.NET itself is a larger framework t
