Controller Service Dependency Injection Issue - Asp.net Framwork

Hello I'm trying to instantiate a class on application startup and then share that instance through dependency injection to a controller. For some reason it won't let me use a Controller Constructor with parameters. It gives the errors:

[MissingMethodException: No parameterless constructor defined for this object.]

and

[InvalidOperationException: An error occurred when trying to create a controller of type 'Project1.Controllers.HomeController'. Make sure that the controller has a parameterless public constructor.]

I've found a couple of people who have had similar issues but I haven't been able to figure out what the exact problem is.

I also left out some of the extraneous code (why it doesn't look like the code actually does anything useful).

Startup.cs

using Project1.Services;

[assembly: OwinStartup(typeof(Project1.Startup))]

namespace Project1
{
    public class Startup
    {
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddSingleton<IPackageScraperService>(new PackageScraperService());
        }

        public void Configuration(IAppBuilder app)
        {
        }
    }
}

IPackageScraperService.cs

using Project1.Services;

namespace Project1.Services
{
    public interface IPackageScraperService
    {
        List<PackageScraperService.Script> GetLoadedScripts();
    }
}

PackageScraperService.cs

namespace Project1.Services
{
  public class PackageScraperService : Services.IPackageScraperService
  {
      public class Script
      {
          public FileAttributes Attibutes { get; set; }

          public string Text { get; set; }
      }


      public List<Script> Scripts;

      public List<Script> GetLoadedScripts()
      {
          return Scripts;
      }   
  }

HomeController.cs

using Project1.Services;

namespace Project1.Controllers
{
    public class HomeController : Controller
    {
        private IPackageScraperService _packageScraperService;

        public HomeController(IPackageScraperService packageScraperService)
        {
            _packageScraperService = packageScraperService;
        }

        public ActionResult Index()
        {
            return View();
        }
    }

}

For anyone else looking for documentation, this tutorial worked for me.
