The following code demonstrates basic usage of task scheduling.

// Define a task which inherits from IScheduledTask interfacepublicclassFooTask:IScheduledTask{publicstringSchedule{get;privateset;}publicFooTask(IConfigurationconfiguration){if(configuration==null){thrownewArgumentNullException(nameof(configuration));}varschedule=configuration["Scheduling:Tasks:FooTask:Schedule"];if(string.IsNullOrWhiteSpace(schedule)){thrownewArgumentException(nameof(schedule));}Schedule=schedule;// Set the cron expression}publicasyncTaskExecuteAsync(CancellationTokencancellationToken){// Write your logic here}}publicclassStartup:IStartup{publicStartup(IConfigurationconfiguration)=>Configuration=configuration;publicIConfigurationConfiguration{get;}publicvoidConfigureServices(IServiceCollectionservices){if(services==null){thrownewArgumentNullException(nameof(services));}vardelay=configuration?.GetValue<TimeSpan>("Scheduling:Delay");services.AddSingleton<IScheduledTask,FooTask>();services.AddScheduler((sender,args)=>args.SetObserved(),delay);}}
