An interface in C#.NET is a contract that any class or struct implementing it must follow. If a class does not implement all the interface members, it must be declared as abstract. This is because the class cannot provide concrete implementations for all the interface members, thus it cannot be instantiated. Interfaces themselves do not allow partial implementation; they require that any implementing class or struct provide implementations for all its members. Interfaces cannot contain static methods or static data; they can only contain method, property, event, and indexers declarations.
