Can I register netcore2 Topshelf application as Windows service on Windows?

Hi,

I understand Topshelf netcore2 support is still in developing. I created a simple Topshelf netcore2 service like below.

  class Program
  {
    static void Main(string[] args)
    {
      var containerBuilder = new ContainerBuilder();
      containerBuilder.RegisterType<ShellService>();


      var container = containerBuilder.Build();


      HostFactory.Run(configurator =>
      {
        configurator.UseAutofacContainer(container);
        configurator.Service<ShellService>(settings =>
          {
            settings.ConstructUsingAutofacContainer();
            settings.WhenStarted(service => service.Start());
            settings.WhenStopped(service => service.Stop());
          }
        );
        configurator.SetDescription("Shell Service");
        configurator.SetDisplayName("Shell Service");
        configurator.SetServiceName("Shell Service");
      });
    }
  }

Then I tried to install the service with an Admin console.

dotnet Nike.Service.Shell.dll install

The error I got was like below.

Topshelf.HostFactory Error: 0 : An exception occurred creating the host, Topshelf.HostConfigurationException: The service was not properly configured:
[Failure] Command Line An unknown command-line option was found: ARGUMENT: install
[Success] Name Shell Service
[Success] ServiceName Shell Service
   at Topshelf.Configurators.ValidateConfigurationResult.CompileResults(IEnumerable`1 results)
   at Topshelf.HostFactory.New(Action`1 configureCallback)
Topshelf.HostFactory Error: 0 : The service terminated abnormally, Topshelf.HostConfigurationException: The service was not properly configured:
[Failure] Command Line An unknown command-line option was found: ARGUMENT: install

   at Topshelf.Configurators.ValidateConfigurationResult.CompileResults(IEnumerable`1 results)
   at Topshelf.HostFactory.New(Action`1 configureCallback)
   at Topshelf.HostFactory.Run(Action`1 configureCallback)

But according to this article, https://docs.microsoft.com/en-us/aspnet/core/host-and-deploy/windows-service?view=aspnetcore-2.1, registering a netcore2 application as a Windows service is possible. So I wonder if I miss anything, or Topshelf has not supported this feature yet.

Thanks,
