如何在asp.net Core1.1中编写微软事件日志？

<ItemGroup>
  <PackageReference Include="Microsoft.Extensions.Logging.EventLog" Version="1.1.2" />
</ItemGroup>

using Microsoft.AspNetCore;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Logging;

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

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

{
  "Logging": {
    "EventLog": {
      "LogLevel": {
        "Default": "Information"
      }
    }
  }
}

using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;

public class HomeController : Controller
{
    private readonly ILogger<HomeController> _logger;

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

    public IActionResult Index()
    {
        _logger.LogInformation("This is an information log message.");
        _logger.LogWarning("This is a warning log message.");
        _logger.LogError("This is an error log message.");

        return View();
    }
}
