An interface is a contract that specifies a set of methods, properties, events, and indexers that a class must implement. It does not provide any implementation details, only the signatures of the members. An interface can be implemented by any class, regardless of its inheritance hierarchy.
On the other hand, an abstract class is a class that cannot be instantiated directly, but is meant to be subclassed. It can contain both abstract and non-abstract members, and can provide partial implementation details for its subclasses. A subclass must implement any abstract members that it inherits from its abstract base class.
the main differences between interfaces and abstract classes are:
