Asp.Net core MVC 2.0 logging

Hello,

Here is what i've done: I have injected an ILogger in my Controller's constructor:

public MyController(ILogger<HomeController> logger)
{
_logger = logger;
}

public IActionResult Index()
{
_logger.LogError("Here is a log message");
return View();
}

And Here is what i've changed in Program.cs:

public static IWebHost BuildWebHost(string[] args) =>
        WebHost.CreateDefaultBuilder(args)
            .ConfigureLogging((hostingContext, logging) =>
            {
               logging.AddConsole();
               logging.AddDebug();
})
            .UseStartup<Startup>()
            .Build();
}

The application is hosted on a Windows Server computer with IIS.
The application works fine but i cannot find where the log is written...

Thanks
