ago, ASP.NET's error handling was one of the major things that made me wonder if ASP.NET MVC could give me something that ASP.NET Web asp.net mvc handleerrorattribute Forms couldn't. Web Forms is based on pages; so if something goes wrong, all that you can do is to redirect the user to another page and explain what the error was or just be generically sorry. ASP.NET Web Forms

confusing topics in ASP.NET MVC 5. There are numerous ways of implementing error pages in ASP.NET MVC 5 and when you search mvc error handling global asax 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 https://www.simple-talk.com/dotnet/asp-net/handling-errors-effectively-in-asp-net-mvc/ (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 https://dusted.codes/demystifying-aspnet-mvc-5-error-pages-and-error-logging 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 the HttpApplication (which is the default han
