For Quartz.AspNetCore with AspNetCoreWebApi projects, in Program.cs add this:

using Quartz;
...
builder.Services.AddQuartz(q =>
{
    var jobKey1 = new JobKey("ContractUpdaterJob");
    q.AddJob<ContractUpdaterJob>(opts => opts.WithIdentity(jobKey1));
    q.AddTrigger(opts => opts
        .ForJob(jobKey1)
        .WithIdentity("ContractUpdaterJob-trigger")
        .WithCronSchedule("0 0 12-19 * * ?")
    );

    var jobKey2 = new JobKey("SpaceMaintenanceJob");
    q.AddJob<SpaceMaintenanceJob>(opts => opts.WithIdentity(jobKey2));
    q.AddTrigger(opts => opts
        .ForJob(jobKey2)
        .WithIdentity("SpaceMaintenanceJob-trigger")
        .WithCronSchedule("0 0 10 * * ?")
    );

});

if you want to add jobs and triggers dynamically you can try the following code.

` using Quartz;

public Task DoSomething(IScheduler schedule, CancellationToken ct)
{
    var job = JobBuilder.Create<StartTripJob>()
                        .WithIdentity("name", "group")
                        .Build();

    var trigger = TriggerBuilder.Create()
        .WithIdentity("name", "group")
        .StartNow()
        .Build();

    await scheduler.ScheduleJob(job, trigger, ct);
}

I use this solution:

IJobDetail jobDetail = JobBuilder
    .Create<ReportJob>()
    .WithIdentity("theJob")
    .Build();

ITrigger everydayTrigger = TriggerBuilder
    .Create()
    .WithIdentity("everydayTrigger")
    // fires 
    .WithCronSchedule("0 0 12 1/1 * ?")
    // start immediately
    .StartAt(DateBuilder.DateOf(DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second, DateTime.Now.Day, DateTime.Now.Month, DateTime.Now.Year))
    .Build();
ITrigger yearlyTrigger = TriggerBuilder.Create()
    .WithIdentity("yearlyTrigger")
    // fires 
    .WithCronSchedule("0 0 12 1 1 ? *")
    // start immediately
    .StartAt(DateBuilder.DateOf(DateTime.Now.Hour, DateTime.Now.Minute, DateTime.Now.Second, DateTime.Now.Day, DateTime.Now.Month, DateTime.Now.Year))
    .Build();

var dictionary = new Dictionary<IJobDetail, Quartz.Collection.ISet<ITrigger>>();
dictionary.Add(jobDetail, new Quartz.Collection.HashSet<ITrigger>()
                          {
                              everydayTrigger,
                              yearlyTrigger
                          });
sched.ScheduleJobs(dictionary, true);

What you want to accomplish is very simple:

ISchedulerFactory schFactory = new StdSchedulerFactory();
IScheduler sch = schFactory.GetScheduler();

sch.Start();

//Repeat the code below for as many jobs you'd like
//creating jobs and triggers for them. 
//If they fire at the same time, just one ITrigger is needed .....
IJobDetail job = JobBuilder.Create<HelloJob>()
    .WithIdentity("myJob", null)
    .Build();

ITrigger trigger = TriggerBuilder
                 .Create()
                 .WithSchedule(SimpleScheduleBuilder.RepeatMinutelyForever())
                 .ForJob(job)
                 .WithIdentity(job.Key.Name + "Trigger")
                 .Build();

sch.AddJob(trigger);

If you're new to Quartz.Net I would suggest you to start with Jay Vilalta's Blog and the old one where you can find loads of tutorials and useful infos about Quartz.Net.

If you want to schedule multiple jobs in your console application you can simply call Scheduler.ScheduleJob (IScheduler) passing the job and the trigger you've previously created:

IJobDetail firstJob = JobBuilder.Create<FirstJob>()
               .WithIdentity("firstJob")
               .Build();

ITrigger firstTrigger = TriggerBuilder.Create()
                 .WithIdentity("firstTrigger")
                 .StartNow()
                 .WithCronSchedule("0 * 8-22 * * ?")
                 .Build();


IJobDetail secondJob = JobBuilder.Create<SecondJob>()
               .WithIdentity("secondJob")
               .Build();

ITrigger secondTrigger = TriggerBuilder.Create()
                 .WithIdentity("secondTrigger")
                 .StartNow()
                 .WithCronSchedule("0 0/2 * 1/1 * ? *")
                 .Build();

Scheduler.ScheduleJob(firstJob, firstTrigger);
Scheduler.ScheduleJob(secondJob, secondTrigger);

You can download a working example here.

UPDATE:

If you want to pause and/or restart a job you can use PauseJob and ResumeJob (you can do the same for a trigger with PauseTrigger and ResumeTrigger).

This is a sample:

private static void Test001(IScheduler Scheduler)
{
    IJobDetail firstJob = JobBuilder.Create<FirstJob>()
                   .WithIdentity("firstJob")
                   .Build();

    ITrigger firstTrigger = TriggerBuilder.Create()
                     .WithIdentity("firstTrigger")
                     .StartNow()
                     .WithSimpleSchedule(x => x.WithIntervalInSeconds(1).RepeatForever())
                     .Build();


    IJobDetail secondJob = JobBuilder.Create<SecondJob>()
                   .WithIdentity("secondJob")
                   .Build();

    ITrigger secondTrigger = TriggerBuilder.Create()
                     .WithIdentity("secondTrigger")
                     .StartNow()
                     .WithSimpleSchedule(x=>x.WithIntervalInSeconds(1).RepeatForever())
                     .Build();


    Scheduler.ScheduleJob(firstJob, firstTrigger);
    Scheduler.ScheduleJob(secondJob, secondTrigger);

    for (int i = 0; i < 300; i++)
    {
    System.Threading.Thread.Sleep(100);
    if (i == 100)
    {
        Scheduler.PauseJob(new JobKey("firstJob"));
    }
    else if (i == 200)
    {
        Scheduler.ResumeJob(new JobKey("firstJob"));
    }
    }
}
