This is the resulting log

                ContentType = "text/html"
            };
        }
    }

    public class Program
    {
        public static void Main(string[] args)
        {
            CreateWebHostBuilder(args).Build().Run();
        }

        public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>
            WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .ConfigureLogging(logging =>
                {
                    logging.AddConsole();
                    logging.AddDebug();
                    logging.SetMinimumLevel(LogLevel.Trace);
                })
                .UseEnvironment("Development");
    }
}

This code is so basic I don't see what could be the problem.

And if I change the controller to the following


    public class HomeControler : Controller
    {
        [HttpGet("/")]
        [HttpGet("[controller]")]
        [HttpGet("[action]")]
        public ActionResult Index()
        {
            return new ContentResult
            {
                Content = @"
                <html><body>
                <b>Hello World running on Endpoint Routing</b>
                <br/><br/>
                    <li><a href=""/"">/</a></li>
                    <li><a href=""/home"">/home</a></li>
                    <li><a href=""/home/index"">/home/index</a></li>
                </ul>
                </body></html>",
                ContentType = "text/html"
            };
        }
    }

It will work on http://localhost:5000/, http://localhost:5000/index but not http://localhost:5000/home.

Could this be because you've misspelled "Controller" in HomeControler?

Yep. It's that.
