Autofac list of types that implements interface / C# Asp.net

问题

I had the problem with Autofac and memory leak in NServiceBus Scheduler. But fortunately I fixed that.

Autofac and memory leak with BeginLifetimeScope / DbContext has been disposed / C# asp.net

But now I'm trying to refactor this part slightly.

My code:

public void Start()
{
    List<Type> jobTypes = new List<Type> { typeof(ExpiryDateTask) };

    foreach (var jobType in jobTypes)
    {
        _schedule.Every(TimeSpan.FromSeconds(30), () =>
        {
            using (var scope = _lifetimeScope.BeginLifetimeScope())
            {
                var job = scope.Resolve<IJob>();
                job.Run();
            }
        });
    }
}

How can I refactor this part:

List<Type> jobTypes = new List<Type> { typeof(ExpiryDateTask) }; - that list should be filled somehow by all Types of Tasks that implement IJob interface.
var job = scope.Resolve<IJob>(); I think this is wrong and should looks more like var job = resolveJob(jobType) - so basically based on the type.

@EDIT

Point (1) solved by Getting all types that implement an interface

For the second part of your question, you can use Autofac child container registrations to do what you want:

foreach (var jobType in jobTypes)
{
    _schedule.Every(TimeSpan.FromSeconds(30), () =>
    {
        using (var scope = _lifetimeScope.BeginLifetimeScope(builder =>
        {
            builder.RegisterType(jobType).As<IJob>();
        }))
        {
            var job = scope.Resolve<IJob>();
            job.Run();
        }
    });
}

That way, classes that implement IJob will also benefit from constructor dependency injection.
