Aspnet Mvc Tutorial
are two elementary and yet very confusing topics in ASP.NET MVC 5. There are numerous ways of implementing error pages in ASP.NET MVC 5 and when aspnet mvc 5 you search 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 (e.g.: 404, 403, 500, etc.) Preserving the HTTP error code in the response to avoid aspnet mvc 4 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 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 Navigatin

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 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 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("
