.net Core Quartz Dependency Injection

You can use the Quartz.Spi.IJobFactory interface and implement it. The Quartz documentations states:

When a trigger fires, the Job it is associated to is instantiated via the JobFactory configured on the Scheduler. The default JobFactory simply activates a new instance of the job class. You may want to create your own implementation of JobFactory to accomplish things such as having your application’s IoC or DI container produce/initialize the job instance.
See the IJobFactory interface, and the associated Scheduler.SetJobFactory(fact) method.

ISchedulerFactory schedulerFactory = new StdSchedulerFactory(properties);
var scheduler = schedulerFactory.GetScheduler();

scheduler.JobFactory = jobFactory;


The implementation can look like this:

public class JobFactory : IJobFactory
    protected readonly IServiceProvider Container;

    public JobFactory(IServiceProvider container)
        Container = container;

    public IJob NewJob(TriggerFiredBundle bundle, IScheduler scheduler)
        return Container.GetService(bundle.JobDetail.JobType) as IJob;

    public void ReturnJob(IJob job)
        // i couldn't find a way to release services with your preferred DI, 
        // its up to you to google such things

To use it with the Microsoft.Extensions.DependencyInjection create your container like this:

var services = new ServiceCollection();
services.AddTransient<IAuthorizable, AuthorizeService>();
var container = services.BuildServiceProvider();
var jobFactory = new JobFactory(container);
