OnStart

Let's take a look at our OnStart method:

public new bool OnStart([CanBeNull] HostControl host)
{
base.Start(host);
_hc = host;
_jobScheduler?.Start();
//_logger?.SendInformation(string.Intern("Job scheduler started"));
// construct a scheduler factory
ISchedulerFactory schedFact = new StdSchedulerFactory();
// get a scheduler
IScheduler sched = schedFact.GetScheduler().Result;
sched.Start();
// define the job and tie it to our HelloJob class
IJobDetail job = JobBuilder.Create<SampleJob>()
.WithIdentity("myJob", "group1")
.Build();
// Trigger the job to run now, and then every 40 seconds
ITrigger trigger = TriggerBuilder.Create()
.WithIdentity("myTrigger", "group1")
.StartNow()
.WithSimpleSchedule(x => x
.WithIntervalInSeconds(40)
.RepeatForever())
.Build();
// Schedule the job
sched.ScheduleJob(job, trigger);
return true;}

What exactly are we doing here? Let's take it one step at a time:

1. The first line we encounter is to instantiate the scheduler from the factory
2. The second...
