How to throw HttpResponseException in ASP 5 (vnext)

In ASP.NET 5 (vnext), you can throw an HttpResponseException to return an HTTP error response from your API endpoint. However, the HttpResponseException class is not available in ASP.NET 5. Instead, you can use the HttpException class to throw an HTTP error response.

Here's an example of how to throw an HTTP error response using the HttpException class:

using Microsoft.AspNetCore.Mvc; public class MyController : ControllerBase { public IActionResult MyAction() { // Throw an HTTP error response throw new HttpException(404, "The resource could not be found."); } }

In this example, we have a MyController class with a MyAction method that throws an HTTP error response with a 404 status code and a message.

When the MyAction method is called, an HTTP error response will be returned to the client with a 404 status code and the specified message.

Note that you will need to import the Microsoft.AspNetCore.Mvc namespace to use the ControllerBase and IActionResult classes. Also, make sure to set the app.UseDeveloperExceptionPage(); in the Configure method in your Startup.cs file to display the detailed error message during development.
