Out of scope

Concepts

• interfaces: know what interfaces are; know how to use interfaces; know how to define an interface; know how to implement an interface; know how to explicitly implement an interface.
• ordering : know how to implement the IComparable<T> interface and what its effect is on the behavior of collections.
• explicit-interfaces: know how an explicit interface is declared; know how use an explicit interface; know why explicit interfaces are useful

Prerequisites

• classes: know how to work with classes.
• properties: know what properties are.
• lists: know how to use List<T>.
