I’m just about to create a WorkQueueService that can handle different type of WorkItems. For each type of WorkItem, I will have an implementation of IWorkItemProcessor. I’m using IoC, so all the IWorkItemProcessor implementations will be registered in the container. My WorkQueueService will need to obtain the appropriate Processor for each WorkItem.

The question is should I make my WorkQueueService depend directly on the the container? Or should I abstract this responsibility into a WorkItemProcessorFactory which would be just a thin wrapper around the IoC container?

What have other people done in this situation, and why?

    It is recommended that you abstract containers by creating factories. Only the factories should be aware of containers. There are two benefits to it:

    1. IOC container since well abstracted by factories; it could be replaced by a better container in future.

    2. Knowledge/Complexity of interacting with IOC container is encapsulated in a well defined factory. All the members on the team need not be aware on the functioning of a particular IOC container.
