How to rerun my job after it's end?

I'm using the Quartz.Net Library. I wrote some trigger:

var t = 
   TriggerBuilder.Create()
   .WithIdentity("FirstTask", "TaskGroup")
   .StartAt(DateBuilder.TodayAt(16, 17, 0))
   .EndAt(DateBuilder.TodayAt(17, 17, 0))
   .WithSimpleSchedule(x => x.RepeatForever()
                             .WithIntervalInSeconds(1))
   .Build();

If I exclude .WithIntervalInSeconds(1) I have an exception that the retry time can't be zero. So, how can I restart my job when it has finished? Also I didn't find the quartz.net configure file to set maximum threads for it.

Much easier than it looked at first:

var job = JobBuilder.Create<HelloJob>().WithIdentity(new JobKey("Task_1", "TaskGroup")).Build();
var t = TriggerBuilder.Create()
        .WithIdentity("Trigger_1", "TaskGroup")
        .StartAt(DateBuilder.TodayAt(21, 15, 0))
        .EndAt(DateBuilder.TodayAt(21, 18, 0))
        .Build();
_scheduleService.Scheduler.ScheduleJob(job, t);

And implementing method in listiner:

public void JobWasExecuted(IJobExecutionContext context, JobExecutionException jobException)
{
    if (DateTime.UtcNow > context.Trigger.EndTimeUtc)
        return;
    context.Scheduler.RescheduleJob(context.Trigger.Key, context.Trigger);
}

In my previous job we configure Quartz threadpool as the following:

quartz.threadPool.threadCount = 3

Read more about it in Configuration section.

@stuartd provide an answer to your question here.
Take his answer and then change the trigger to use StartNow method:

var trigger = TriggerBuilder.Create()
                            .WithIdentity(triggerKey)
                            .startNow()
                            .build();

@SchlaWiener also provide a nice solution using TopShelf.

To set max thread count to 50:

var properties = new NameValueCollection { { @"quartz.threadPool.threadCount", @"50" } };
var factory = new StdSchedulerFactory(properties);
var scheduler = schedulerFactory.GetScheduler();

And do not exclude WithIntervalInSeconds, Quartz must know, when to run again
