I have deployed the site to IIS, but when visiting it with the browser, it shows me this: Server Error 500 - Internal server error. There is a problem with the resource you are looking for, and it cannot be displayed. After fiddling around with the web.config, I now get: The page

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 it 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 aspnet mvc 3 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 http://stackoverflow.com/questions/5385714/deploying-website-500-internal-server-error 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 https://dusted.codes/demystifying-aspnet-mvc-5-error-pages-and-error-logging 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, Working with Multiple Environments Hosting Managing Application State Servers Request Features Open Web Interface for .NET (OWIN) Choosing the Right .NET For https://docs.asp.net/en/latest/fundamentals/error-handling.html You on the Server MVC Testing Working with Data Client-Side Development Mobile Publishing and Deployment Guidance for Hosting Providers Security Performance Migration API Contribute ASP.NET http://www.khalidabuhakmeh.com/asp-net-mvc-custom-errors-are-broken-but-here-is-the-fix Docs » Fundamentals » Error Handling Edit on GitHub Warning This page documents version 1.0.0-rc1 and has not yet been updated for version 1.0.0 Error aspnet mvc Handling¶ By Steve Smith When errors occur in your ASP.NET app, you can handle them in a variety of ways, as described in this article. Sections Configuring an Exception Handling Page Using the Developer Exception Page Configuring Status Code Pages Limitations of Exception Handling During Client-Server Interaction Server Exception asp.net mvc 500 Handling Startup Exception Handling ASP.NET MVC Error Handling 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 mechani During development, we want to see the yellow screen of death early and often to ensure users don't see the error pages at all. I've personally added custom errors to many web applications, and even wrote about it in a previous post. In a new application, I decided to take a different approach than described in my previous post. I was surprised that my previous approach would not work. This post will describe the initial approach, why it failed, and how to get what I wanted. It also is a culmination of 8+ hours of pure pain that I hope you can avoid. The Broken Approach When errors occur, I like to use the existing url and return the appropriate HTTP status code. To do this, I used the customErrors section as recommended by most in the ASP.NET space. Here is what the section looks like. Aspnet Mvc Cms
