How do I create a Quartz.NET’s job requiring injection with autofac

I am trying to get Quartz.net (2.1.2) to work with an IoC container (autofac), as I have services I need to use in the scheduled jobs. I have found similar posts on the subject, but I can't seem to find one with a specific registration example for autofac.

In the following example, the "HelloJob" will run, but whenever I try to inject the releaseService into the "ReleaseJob" it refuses to run. If I remove the ReleaseService references from the ReleaseJob it will then work.

The part I believe I have wrong is the bindings. I'm not very experienced with them, but I've tried every possible thing I can think of and it just refuses to work.

I marked the code in the DependencyRegistration.cs section where I believe the issue is.

Note that I have also tried getting the scheduler in the DependencyRegistration.cs file with:

//Schedule
IScheduler scheduler = container.Resolve<ISchedulerFactory>().GetScheduler();

...instead of using a new StdSchedulerFactory(), but that doesn't work either.

Update:
Some related links that are related to what I need to do and might help (I've already gone through them all but still cannot figure out how to get it working with autofac):

I finally tracked down what the issue was.

My release service was using a data repository which was being created with a different scope.

I discovered this by creating a new test service that did nothing but return a string, and that worked being injected into a quartz job.

On discovering this, I changed the scope of the repository called upon by the release service , and then the release service started working inside the quartz job.

My apologies to anyone that looked at this question to try and help me out. Because the code of the release service was not listed, it would have been difficult to figure out what was wrong.

I have updated the code with the final working bindings I used for quartz with autofac.
