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.

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("

With the detailed error, you can locate the real issue here. Also, if you can run the browser on the server, you get details on the error, because the server recognizes that you are local and shows it to you. Or if you can read the log of the server using the Event Viewer, you also see the details of your error. On IIS 6
