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.Query.ContainsKey("throw")) { throw new Exception("Exception triggered!"); } var builder = new StringBuilder(); builder.AppendLine("
Hello World!"); builder.AppendLine("- "); builder.AppendLine("
- Throw Exception"); builder.AppendLine("
- Missing Page"); builder.AppendLine(""); builder.AppendLine("

How to: Handle Application-Level Errors Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET Framework 3.0 Visual Studio 2005 This code example shows how to create an error handler http error handling in the Global.asax file that will catch all unhandled ASP.NET errors while processing a request — in other words, all the errors that are not caught with a Try/Catch block or in a page-level error handler. In the example, the handler transfers control to a generic error page named GenericErrorPage.aspx, which interprets the error and displays an appropriate message. Example The following example is from a complete code sample in Complete Example for Error Handlers. Security Note Never set customErrors to Off in your Web.config file if you do not have an Application_Error handler in your Global.asax file. Potentially compromising information about your Web site can be exposed to anyone who can cause an error to occur on your site. C#VB Copy void Application_Error(object sender, EventArgs e) { // Code that runs when an unhandled error occurs // Get the exception object. Exception exc = Server.GetLastError(); // Handle HTTP errors if (exc.GetType() == typeof(HttpException)) { // The Complete Error Handling Example generates // some errors using URLs with "NoCatch" in them; // ignore these here to simulate what would happen // if a global.

I'm using MVC2 and .NET 4.0 (started the 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-dir/non-existent-file.txt Controller not found: /non-existent-con
