.NET Design Patterns Tutorial - For Beginners & Professionals

Understanding MVC, MVP and MVVM Design Patterns

There are three most popular MV-* design patterns: MVC, MVP and MVVM. These are widely used by the various technologies. In this article, I will provide my opinion on these three.

 

Command Design Pattern - C#

Command pattern falls under Behavioural Pattern of Gang of Four (GOF) Design Patterns in .Net. The command pattern is commonly used in the menu systems of many applications such as Editor, IDE etc. In this article, I would like share what is command pattern and how is it work?

 

Chain of Responsibility Design Pattern - C#

Chain of Responsibility pattern falls under Behavioural Pattern of Gang of Four (GOF) Design Patterns in .Net. The chain of responsibility pattern is used to process a list or chain of various types of request and each of them may be handle by a different handler. In this article, I would like share what is chain of responsibility pattern and how is it work?

 

Proxy Design Pattern - C#

Proxy pattern falls under Structural Pattern of Gang of Four (GOF) Design Patterns in .Net. The proxy design pattern is used to provide a surrogate object, which references to other object. In this article, I would like share what is proxy pattern and how is it work?

 

Flyweight Design Pattern - C#

Flyweight pattern falls under Structural Pattern of Gang of Four (GOF) Design Patterns in .Net. Flyweight pattern try to reuse already existing similar kind objects by storing them and creates new object when no matching object is found. In this article, I would like share what is flyweight pattern and how is it work?

 

Facade Design Pattern - C#

Facade pattern falls under Structural Pattern of Gang of Four (GOF) Design Patterns in .Net. The Facade design pattern is particularly used when a system is very complex or difficult to understand because system has a large number of interdependent classes or its source code is unavailable. In this article, I would like share what is facade pattern and how is it work?

 

Decorator Design Pattern - C#

Decorator pattern falls under Structural Pattern of Gang of Four (GOF) Design Patterns in .Net. Decorator pattern is used to add new functionality to an existing object without changing its structure. Hence Decorator pattern provides an alternative way to inheritance for modifying the behavior of an object. In this article, I would like share what is decorator pattern and how is it work?

 

Composite Design Pattern - C#

Composite pattern falls under Structural Pattern of Gang of Four (GOF) Design Patterns in .Net. Composite Pattern is used to arrange structured hierarchies. In this article, I would like share what is composite pattern and how is it work?

 

Bridge Design Pattern - C#

Bridge pattern falls under Structural Pattern of Gang of Four (GOF) Design Patterns in .Net. All we know, Inheritance is a way to specify different implementations of an abstraction. But in this way, implementations are tightly bound to the abstraction and can not be modified independently.

 

Adapter Design Pattern - C#

Adapter pattern falls under Structural Pattern of Gang of Four (GOF) Design Patterns in .Net. The Adapter pattern allows a system to use classes of another system that is incompatible with it. It is especially used for toolkits and libraries. In this article, I would like share what is adapter pattern and how is it work?

 

Singleton Design Pattern - C#

Singleton pattern is one of the simplest design patterns. This pattern ensures that a class has only one instance and provides a global point of access to it.

 

Prototype Design Pattern - C#

Prototype pattern is used to create a duplicate object or clone of the current object to enhance performance. This pattern is used when creation of object is costly or complex.

 

Builder Design Pattern - C#

Builder pattern builds a complex object by using simple objects and a step by step approach. Builder class builds the final object step by step. This builder is independent of other objects. The builder pattern describes a way to separate an object from its construction. The same construction method can create different representation of the object.

 

Abstract Factory Design Pattern - C#

Abstract Factory method pattern falls under Creational Pattern of Gang of Four (GOF) Design Patterns in .Net. It is used to create a set of related objects, or dependent objects. Internally, Abstract Factory use Factory design pattern for creating objects. It may also use Builder design pattern and prototype design pattern for creating objects.

 

Factory Method Design Pattern - C#

In Factory pattern, we create object without exposing the creation logic. In this pattern, an interface is used for creating an object, but let subclass decide which class to instantiate. The creation of object is done when it is required. The Factory method allows a class later instantiation to subclasses.
