In this article you will learn about the basics of Object Oriented Programming (OOP).

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 article explains the important key points of interfaces in C#. Learn what is interface, why we need an interface, how to define a C# interface.

This article explains the important key points of Abstract Class in C#. Learn what is an Abstract Class, how to define an Abstract Class, and why do we need an Abstract Class.

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

Abstract classes are those classes which can't be initiated, that is, they are considered as incomplete classes. Let's learn the concepts of Abstract Classes and Interface in OOP.

This is a basic example of Abstraction vs Encapsulation we read in books, but it becomes very confusing when you try to search them online and explain from a technical perspective.

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

In part 1 of this article, I explained how to implement proper data encapsulation. In part 2 I want to talk about encapsulating business logic. I see this missing in a lot of type design, especially w

As the title specify we will be Replacing the conditional if and Switch statement with the help of Polymorphism using DI container and talk about the benefits of doing the same in this article. Oops g

Encapsulation is one of the fundamentals of OOP (object-oriented programming). It refers to the bundling of data with the methods that operate on that data. Encapsulation is used to hide the values or

The relationship between objects defines how these objects will interact or collaborate to perform an operation in an application.

Mixin is an object oriented programming concept that has been used successfully in the enterprise application development scenarios. In an object oriented programming language, Mixin is a class which

The below post is based on one of the question I answered on StackOverflow, in which the questioner wants to cancel a task when its taking too long to respond; i.e., taking too much time in execution

In this video learn about static keyword in C#. This video has code walkthrough for C# static examples. BY the end of this video, you will be able to understand about the static keyword in c#.

This article is a brief introduction to OOP. The basic building blocks of object-oriented programming are the class and the object. A class acts as a blueprint/template to create the instances/objects

Here I explore an Interface Vs an Abstract Class. An interface can only have a declaration but not a definition. An interface can only have methods, properties, indexers and events whereas a class can

This article explains access specifiers in C#. Access modifiers and specifiers are keywords to specify the accessibility of a type and its members. C# has 5 access specifier or access modifier keyword

This video helps to understand the similarities and differences between Interface & Abstract class in C#. Which one to choose, what are their purpose

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 &qu

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