Remotely connect to .net core self hosted web api

Question

I have a simple .net core web api with one action:

[Route(\"[action]\")]
public class APIController : Controller
{
    // GET api/values
    [HttpGet]
    pu

My guess is that the issue isn't in your controller, it is in program.cs. You need to modify the construction of your WebHost

var host = new WebHostBuilder()
.UseKestrel()
.UseContentRoot(Directory.GetCurrentDirectory())
.UseUrls("http://localhost:5000", "http://odin:5000", "http://192.168.1.2:5000")
.UseIISIntegration()
.UseStartup()
.Build();

Unless you add the UseUrls line, Kestrel isn't going to listen outside of localhost. This makes sense, because in a normal situation Kestrel will be sitting behind a reverse proxy like IIS or NGNIX and doesn't need to bind to external URLs.
