Can i create service in different class and call in main()? Yes. All you have to do is configure them like this: public static IHostBuilder CreateHostBuilder( string [] args) => Host.CreateDefaultBuilder(args) .ConfigureServices((hostContext, services) => { services.AddHostedService (); services.AddHostedService (); services.AddHostedService (); });

You can use BackgroundService to create a service in .NET Core console app or even in ASP.NET Core app: https://docs.microsoft.com/en-us/aspnet/core/fundamentals/host/hosted-services?view=aspnetcore-2.2&tabs=visual-studio If you are using Visual Studio 2019 with .NET Core 3, you should be able to use the template WorkerService project to get started. https://wakeupandcode.com/worker-service-in-asp-net-core/ Here's a quick example: using Microsoft.Extensions.Hosting; using Microsoft.Extensions.Logging; using System; using System.Threading; using System.Threading.Tasks; namespace WorkerServiceDemo { public class Worker : BackgroundService { private readonly ILogger _logger; public Worker(ILogger logger) { _logger = logger; } protected override async Task ExecuteAsync(CancellationToken stoppingToken) { while (!stoppingToken.IsCancellationRequested) { _logger.Log(LogLevel.Information, "Worker running at: {time}" , DateTimeOffset.Now); await Task.Delay(2000, stoppingToken); } } } } Then you can call and register that service in Program class like this: public class Program { public static void Main( string [] args) { CreateHostBuilder(args).Build().Run(); } public static IHostBuilder CreateHostBuilder( string [] args) => Host.CreateDefaultBuilder(args) .ConfigureServices((hostContext, services) => { services.AddHostedService (); }); }
