Answer 1

Create a JobFactory that uses Ninject

public class NinjectJobFactory : IJobFactory
{
    private readonly Func<Type, IJob> jobFactory;

    public NinjectJobFactory (Func<Type, IJob> jobFactory)
    {
        this.jobFactory = jobFactory;
    }

    public IJob NewJob(TriggerFiredBundle bundle)
    {
        return this.jobFactory(bundle.JobDetail.JobType);
    }
}

and a QuarzSchedulerProvider

public class QuartzSchedulerProvider : Provider<IScheduler> 
{
    private readonly IJobFactory jobFactory;
    private readonly IEnumerable<ISchedulerListener> listeners;
    private readonly ISchedulerFactory schedulerFactory;

    public QuartzSchedulerProvider(
        ISchedulerFactory schedulerFactory,
        IJobFactory jobFactory, 
        IEnumerable<ISchedulerListener> listeners)
    {
        this.jobFactory = jobFactory;
        this.listeners = listeners;
        this.schedulerFactory = schedulerFactory;
    }

    protected override IScheduler CreateInstance(IContext context)
    {
        var scheduler = this.schedulerFactory.GetScheduler();
        scheduler.JobFactory = this.jobFactory;
        foreach (var listener in this.listeners)
        {
            scheduler.AddSchedulerListener(listener);
        }

        return scheduler;
    }
}

and a SchedulerFactoryProvider

public class QuartzSchedulerFactoryProvider : Provider<ISchedulerFactory>
{
    protected override ISchedulerFactory CreateInstance(IContext context)
    {
        var properties = new NameValueCollection();
        properties["quartz.dataSource.DataSource.connectionString"] = "Your connection string";
        properties["quartz.dataSource.DataSource.provider"] = "Your provider";

        properties["quartz.jobStore.type"] = "Quartz.Impl.AdoJobStore.JobStoreTX, Quartz";
        properties["quartz.jobStore.driverDelegateType"] = "Quartz.Impl.AdoJobStore.StdAdoDelegate, Quartz ";
        properties["quartz.jobStore.tablePrefix"] = "QRTZ_";
        properties["quartz.jobStore.dataSource"] = "DataSource";
        properties["quartz.jobStore.useProperties"] = "true";

        return new StdSchedulerFactory(properties);
    }
}

and configure

Bind<IJobFactory>().To<NinjectJobFactory>();
Bind<ISchedulerFactory>().ToProvider<QuartzSchedulerFactoryProvider>();
Bind<IScheduler>().ToProvider<QuartzSchedulerProvider>().InSingletonScope();
Bind<Func<Type, IJob>>().ToMethod(ctx => t => (IJob)ctx.Kernel.Get(t));

If you need some ISchedulerListener e.g. for logging bind them here too.

Inject an instance of IScheduler where you want to add Jobs and most likely you have to do property injection of an instance into global.asax too. But note I havn't used Quarz in MVC context yet as I think Scheduled Tasks do not belong into a Web App but rather into a service running on the same server.

Thanks so much Remo :),let me try it – Neurotic

@Remo: should this.ResolutionRoot near the top be this.kernel or did you intend to rename the var? (or is ResolutionRoot something in IJobFactory?) – Michelson

Yes you are right. I'didn't rename everything when I copied it from my solution. I normally use IResolutionRoot instead of IKernel. – Sigvard

@Remo: Makes sense, I like the idea. (HAD SAID: Have taken the liberty of editing the answer). Didnt, can you do it (dont know if IResolutionRoot is resolvable or whether you ctor inject IKernel and then downcast and stash that). (And I personally would demand a Func<JobType,IJob> and use that in the factory). Having said all that, you could just leave it as it illustrates the principle Just Fine Right Now. – Michelson

@Ruben Bartelink: You are absolute right. Passing a Func is even better. I'll update the answer – Sigvard

If you were execute a simple job using this DI implementation in global.asax, what would it look like? – Imaginable

I believe scheduler.AddSchedulerListener(listener); should be scheduler.ListenerManager.AddSchedulerListener(listener); – Toscano
