Abstract Classes manifest couple of features as;
C# allows both classes and function to be declared abstract by using abstract keyword.
You can't create an instance of an abstract class .An abstract member has a signature but no function body and they must be overridden in any non-abstract derived class.
Abstract classes exist primarily for inheritance. Member functions, properties, indexer can be abstract.
A class with one or more abstract members must be abstract as well.
Static members can't be abstract.
