Empty Windows Service can't be run (timeout everytime)

Question

This is my whole service

using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;
using System.Threading;
using System.Threading.Tasks;



var host = Host.CreateDefaultBuilder(args)
    .ConfigureServices((hostContext, services) =>
    {
        services.AddHostedService<Worker>();
    })
    .Build();

await host.RunAsync();

public class Worker : BackgroundService
{


    public Worker()
    {
    }

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        while (!stoppingToken.IsCancellationRequested)
        {
            await Task.Delay(1000, stoppingToken);
        }
    }
}

I register it with sc.exe create and I run it with sc.exe start. I am running it with admin access in cmd. I keep getting this error: The service did not respond to the start or control request in a timely fashion.

What am I doing wrong?

You need to configure your app to be run as a windows service, first need to add this package:

Microsoft.Extensions.Hosting.WindowsServices

And in the Program.cs:

HostApplicationBuilder builder = Host.CreateApplicationBuilder(args);

builder.Services.AddWindowsService(options =>
{
    options.ServiceName = ".NET Joke Service";
});

builder.Services.AddHostedService<Worker>();

Here is a very good guideline for creating windows service by Microsoft:
