Abstraction in DotNetFramework

It is the concept of hiding complex implementation details and showing only the essential features of an object.

It allows you to define abstract classes or interfaces that expose only the required behavior, enabling cleaner and more maintainable code.

In C#, this can be achieved using the abstract keyword for classes and methods, or through interfaces using the interface keyword.

For example, an abstract class Shape might define a method Draw() without specifying how each shape (circle, square...) is drawn, leaving the specifics to the derived classes. This principle supports loose coupling, polymorphism, and code reusability. You can explore more in Microsoft’s official C# Abstraction documentation.
