Often established in projects are ways of doing things, recipes that we follow every time we implement certain aspects of our systems. These can often be automated and put to work as conventions. A good example of this is the configuration of the relationship between an interface and its implementations. One convention that you might find is that the ISomething interface has a default implementation called Something.
