    {
        options.Period = TimeSpan.FromSeconds(5);
        options.UseHandler<Work>();
    });

public class Work : IWorkHandler
{
    public void DoWork()
    {
        Console.WriteLine("Test!");
    }

{
  private readonly CircleControl _circle;

  public HomeController(CircleControl circle)
  {
      _circle = circle;
  }

  public IActionResult Stop()
  {
      _circle.Stop();
      return Ok();
  }
