How do I force a quartz.net job to restart intervall after completion

Question

I have a project where I use TopShelf and TopShelf.Quartz

Following this example I am building my jobs with

                s.

A job listener as proposed by @NateKerkhofs will work, like this:

public class RepeatAfterCompletionJobListener : IJobListener
{
    private readonly TimeSpan interval;

    public RepeatAfterCompletionJobListener(TimeSpan interval)
    {
        this.interval = interval;
    }

    public void JobExecutionVetoed(IJobExecutionContext context)
    {
    }

    public void JobToBeExecuted(IJobExecutionContext context)
    {
    }

    public void JobWasExecuted(IJobExecutionContext context, JobExecutionException jobException)
    {
       string triggerKey = context.JobDetail.Key.Name + ".trigger";

        var trigger = TriggerBuilder.Create()
                .WithIdentity(triggerKey)
                .StartAt(new DateTimeOffset(DateTime.UtcNow.Add(interval)))
                .Build();

        context.Scheduler.RescheduleJob(new TriggerKey(triggerKey), trigger);
    }

    public string Name
    {
        get
        {
            return "RepeatAfterCompletionJobListener";
        }
    }
}

Then add the listener to the scheduler:

var jobKey = "myJobKey";
var schedule = new StdSchedulerFactory().GetScheduler();
listener = new
   RepeatAfterCompletionJobListener(TimeSpan.FromSeconds(5));

schedule.ListenerManager.AddJobListener
         (listener, KeyMatcher.KeyEquals(new JobKey(jobKey)));

var job = JobBuilder.Create(MyJob)
                .WithIdentity(jobKey)
                .Build();

// Schedule the job to start in 5 seconds to give the service time to initialise
var trigger = TriggerBuilder.Create()
                .WithIdentity(CreateTriggerKey(jobKey))
                .StartAt(DateTimeOffset.Now.AddSeconds(5))
                .Build();

schedule.ScheduleJob(job, trigger);

Unfortunately I don't know how to do this (or if it can be done) with the fluent syntax used by Typshelf.Quartz library, I use this with TopShelf and regular Quartz.Net.
