This article defines Object Oriented Programming concepts in C# including Abstraction, Encapsulation, Inheritance and Polymorphism. Includes Code Examples in C# and .NET.

This article explains the important key points of interfaces.

This article is the first part of the series "Abstract Class & Interface: Two Villains of Every Interview" and explains the important key points of Abstract Class.

This article is mainly intended for those already familiar with Object Oriented Programming (OOP) conceptually but are unable to link it with the real world and the programming world.

This tutorial will try to explain the difference between Abstract Class and interface theoretically and programmatically both ways.

This article explains how to build and consume a Class Library (DLL) in C#.

This blog shows the similarities between Class and Struct.

Concept Of Factories In Object Oriented Programming.

Encapsulation is the first pillar of Object Oriented Programming (OOP), yet most code that I see does not implement encapsulation correctly or not all. Like I say in many of my conference sessions ...

In this blog, we are trying to understand one of the important object oriented features of C# language.

In this blog, you will learn about abstract class.

In this blog, we will see why encapsulation is important in an Object Oriented programming language.
