Abstract is a concept in the Object-oriented programming and since C# is an object-oriented programming language that is why it has an abstraction and a keyword abstract. The abstract keyword must be used on the class before you can call override keyword on the members of it. You make a class abstract to tell the developer that once he has inherited from the base-(abstract)-class he is required to override the functions to add the body to them. You cannot override members if the class is not abstract; virtual is also another keyword that allows you to let the developer override the members.
