Asp.net Error Handling Best Practices
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 Handling Startup Exception Handling ASP.NET MVC Error Handling View or download sample code Configuring asp.net error page 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.AppendL

Complete Example for Error Handlers Other Versions Visual Studio 2010 .NET Framework https://msdn.microsoft.com/en-us/library/bb397417.aspx 4 Visual Studio 2008 This code example includes elements for both page-level and application-level exception handling. Code Example Files The example consists of the following files: Web.config Global.asax Default.aspx ExceptionUtility (to be put in the App_Code folder) GenericErrorPage.aspx HttpErrorPage.aspx Http404ErrorPage.aspx DefaultRedirectErrorPage.aspx Web.config The following example shows the Web.config file. The customErrors section specifies how to handle errors that occur with file types that are mapped to ASP.NET, such as .aspx, .asmx, and .ashx files. (In IIS 6.0 and in IIS 7.0 in classic mode, static content files such as .html and .jpg files are not mapped to ASP.NET.) The settings in the example customErrors section cause any unhandled HTTP 404 (file not found) errors to be directed to the Http404ErrorPage.aspx file. These HTTP 404 errors would occur if a request were made for an .aspx file, .asmx file, and so on and if the requested file did not exist. All other unhandled errors in ASP.NET files are directed to the DefaultRedirectErrorPage.aspx file. If

I have tried so many things, but nothing implements IActionResult. I don't understand why this isn't a common thing that people need. If there truthfully is no solution can someone tell me why? I do see some documentation out there using HttpResponseException(HttpResponseMessage), but in order to use this I have to install the compat shim. Is there a new way of doing these things in Core 1.0? Here is something I have been trying with the shim but it isn't working: // GET: api/customers/{id} [HttpGet("{id}", Name = "GetCustomer")] public IActionResult GetById(int id) { Customer c = _customersService.GetCustomerById(id); if (c == null) { var response = new HttpResponseMessage(HttpStatusCode.NotFound) { Content = new StringContent("Customer doesn't exist", System.Text.Encoding.UTF8, "text/plain"), StatusCode = HttpStatusCode.NotFound }; throw new HttpResponseException(response); //return NotFound(); } return new ObjectResult(c); } When the HttpResponseException is thrown, I look on the client and can't find the message I am sending
