Quartz.NET implementation doesn't jive with tutorials

I attempted to implement a very simple Quartz.net implementation using this tutorial ``` using Quartz; using Quartz.Impl; // construct a scheduler factory ISchedulerFactory schedFact = new StdSchedulerFactory(); // get a scheduler IScheduler sched = schedFact.GetScheduler(); sched.Start(); // construct job info JobDetail jobDetail = new JobDetail("myJob", null, typeof(HelloJob)); // fire every hour Trigger trigger = TriggerUtils.MakeHourlyTrigger(); // start on the next even hour trigger.StartTimeUtc = TriggerUtils.GetEvenHourDate(DateTime.UtcNow); trigger.Name = "myTrigger"; sched.ScheduleJob(jobDetail, trigger); ``` The problem I am running into is (for example) `MakeHourlyTrigger` is not available in the Intellisense, and gives me the error Quartz.TriggerUtils does not contain a definition for 'MakeHourlyTrigger'. I get errors on types such as `JobDetail`: "The type or namespace name 'JobDetail' could not be found (are you missing a using directive or an assembly reference?)" Maybe I'm tired and missing something stupid and easy... I hope that's the case. All of the examples I have seen on the Internets say that I should be using Quartz and using Quartz.Impl. Please tell me that I'm just missing something easy...
