View or download sample code Configuring an Exception Handling Page¶ You configure the pipeline for each request in the Startup class's Configure() method (learn more about Application Startup). You can add a simple exception page, meant only for use during development, very easily. All that's required is to add a dependency on Microsoft.AspNetCore.Diagnostics to the project and then add one line to Configure() in Startup.cs: public void Configure(IApplicationBuilder app, IHostingEnvironment env) { app.UseIISPlatformHandler(); if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } The above code includes a check to ensure the environment is development before adding the call to UseDeveloperExceptionPage. This is a good practice, since you typically do not want to share detailed exception information about your application publicly while it is in production. Learn more about configuring environments. The sample application includes a simple mechanism for creating an exception: public static void HomePage(IApplicationBuilder app) { app.Run(async (context) => { if (context.Request.Q

I'm using MVC2 and .NET 4.0 (started the http://stackoverflow.com/questions/4911212/how-to-implement-proper-http-error-handling-in-net-mvc-2 project before MVC3 was released; we'll upgrade after we deliver our initial release). At this point, I'll be happy to properly handle 404 and 500 errors -- 403 (authorization required) would be great, too, followed by various other specific responses. Right now, I either get all 404s, all 500s, all 302s before the 404, or all 302s before the 500. Here are my requirements (which should be pretty close to the basic requirements of HTTP): If a resource is not found, throw a 404, and display a 404-specific page with the requested URL. DO NOT return an intermediate response code like 302. Ideally, keep the requested URL, rather than showing a new URL like /Error/NotFound -- but if the latter displays, be sure we didn't return a redirect response to get it. If an internal server error occurred, throw a 500, and display a 500-specific error with some indication of what went wrong. Again, don't return an intermediate response code, and ideally don't change the URL. Here's what I'd consider a 404: Static file not found: /Content/non-existent-
Effectively in ASP.NET MVC 10 April 2014Handling Errors Effectively in ASP.NET MVCASP.NET MVC gives you more options in https://www.simple-talk.com/dotnet/asp-net/handling-errors-effectively-in-asp-net-mvc/ the way that you handle exceptions. Error handling isn't intrinsically exciting, but there are many ways of avoiding the classic yellow page of death, even getting ELMAH to manage error handling for you. 79 3 Dino Esposito Years ago, ASP.NET's error handling was one of the major things that made me wonder if ASP.NET MVC could give me something aspnet mvc that ASP.NET Web 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 allow you to map an error page for each possible HTTP status code. You control the error handling asp.net mapping through the
