Csharp Quartz调度程序不调用作业(job)类

我是C#的新手，我一直在努力学习Quartz调度器.我一直在try 执行下面的代码，但我怀疑为什么调度程序没有进入HelloJob类.我是不是做错了什么？

如果这是一个愚蠢的错误，但现在一段时间内没有任何积极的结果，我深表歉意.

这是我的代码:

public class Program
{
    public static async Task Main(string[] args)
    {
        StdSchedulerFactory factory = new StdSchedulerFactory();
        IScheduler scheduler = await factory.GetScheduler();
            
        CancellationToken stoppingToken = CancellationToken.None;
            
        await DoSomething(scheduler, stoppingToken);
    }

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

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

        await Console.WriteLineAsync("Job is still in Main class")
        await scheduler.ScheduleJob(job, trigger, ct);
    }
}

public class HelloJob : IJob
{
    public async Task Execute(IJobExecutionContext context)
    {
        await Console.WriteLineAsync("Job Entered HelloJob class")
    }
}
