The Power of WorkItems, Events, and Services
A good podcast. I found to be useful in deciding when to use events vs. services. In our shop, we pretty much use the WorkItem as a use case - something Peter Provost cautions against.
We’ve described a bunch of abstract WorkItem base classes kind of organized around feature-types. So we have a SearchWorkItem that a developer inherits to implement a search feature. The workitem contains the feature-level data (overriden abstract properties) such as display name, key, etc. Generally these WorkItems are only responsible for controlling the display (e.g. putting a view in the Items collection) and holding the state.
We try to put all business logic into CAB Services which are called by the various View Controllers (we use MVC).
