Program.cs

using System.IO;
using System;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;

namespace SampleApp {
	class Program {
		static void Main(string[] args) {
		
			 var builder = new HostBuilder()
				// Setup configuration of the application
				.ConfigureAppConfiguration((appConfig) => {
				    appConfig.Sources.Clear();
					appConfig.SetBasePath(Path.Join(Directory.GetCurrentDirectory(), "config"))
					.AddJsonFile("appsettings.json")
					.AddJsonFile("appsettings.private.json");
				})
				.ConfigureLogging((hbc, logger) => {
				    logger.AddConsole();
				    logger.AddConfiguration(hbc.Configuration.GetSection("Logging"));
				})
				.ConfigureServices((ctx, services) => {
				    services.AddOptions()
					    .AddScheduler()
					    .AddTransient<SERIVCE_HERE>()
					    .Configure<OPTIONS_CLASS_HERE>(ctx.Configuration)
				})
				.UseConsoleLifetime();


			    var host = builder.Build();

			
			    // Example configuring the services collection
			    host.Services.UseScheduler(scheduler => {
				scheduler
					.Schedule<SOME_SCHEDULE_SERVICE>()
					.EveryThirtySeconds()
					.PreventOverlapping("HotFolder");
			    });

			    using (host) {
				await host.StartAsync();

				await host.WaitForShutdownAsync();
