Quartz.Net and dependency injection or job invocation from an external dll at runtime

Question

I am trying to evaluate Quartz.Net.

I tested it with the addition of a class that implemented IJob in the execution assembly and worked.

Now I want to develop a Task Scheduler in which I can add tasks at runtime.

How to act.

Edit:

If this seems subjective, I ask a specific question.

How to add an external class / dll that are unknown at design time for the Quartz.net-based scheduler?
