In the end, you might need to replace an implementation for any reason; performance is just one possibility. Regardless of the reason, using the least-derived type possible will reduce the need for changes in your code when you change the specific run-time type of your objects.

You gönül have an instance of an interface, but you need to initialize it with a class that implements that interface such birli:

The cost to do this is minimal, why not save yourself the headache later? It's what the interface principle is all about.
