ASP .NET Web API throw new HttpResponseException always returns 500

Question

I´m trying to do this

throw new HttpResponseException(HttpStatusCode.Unauthorized); // 401

But this always returns 500(Internal server Error).

Example code:

using System.Net;
using Microsoft.AspNetCore.Mvc;
using System.Web.Http;


namespace Gral_WebAPI.Controllers
{
    [Produces("application/json")]
    public class LoginController : ApiController
    {
        [Microsoft.AspNetCore.Mvc.HttpGet]
        [Microsoft.AspNetCore.Mvc.Route("[action]")]
        public string GitTest()
        {
            throw new HttpResponseException(HttpStatusCode.Unauthorized); // 401
        }
    }
}

Anyone could help me?

why are you mixing .net core and classic asp.net?

You could use return StatusCode(401); instead. You should avoid using exceptions to control the flow of your application.

Do you have any middleware that's intercepting the exception and overriding the status code to 500?

What is the URI you are using to access your action?

I´m calling this: localhost:59580/GitTest I´m using swagger and this is my Startup.cs codeshare.io/adjoEe

@MMachado, assuming you're using default routing rules the URI for this action is /Login/GitTest.

There is always some debate about whether an exception should be used in this way. Purest say an exception should be exceptional, but pragmatists use what works best.
