Design Patterns : Strategy Pattern

If there is one thing that is constant in every software development projects, then it has to be CHANGE. Requirements evolve overtime and you might end up with fairly different set of requirements that you initially started of. As developers one has to be aware of the possibility of change and design applications that are flexible … Continue reading Design Patterns : Strategy Pattern

Design Patterns : Adapter Pattern

There is already a large amount of literature on the Internet which discusses Adapter Pattern. However, the purpose of article is to showcase the implementations of the Adapter Pattern, rather than discussing the application of the pattern. In this post, adapter class is implemented using 1. Inheritance 2. Dependency Injection 3. Generics Consider your old … Continue reading Design Patterns : Adapter Pattern

SOLID : Open / Closed Principle

The Open / Closed Principle focuses on one basic requirement, the classes should be Open for extensions, but closed for modification. The better way to explain the principle would be to first express the issue in hand. Consider the below class. The class itself looks good, but what if in future one needs to add … Continue reading SOLID : Open / Closed Principle

SOLID : Single Responsibility Principle

While OOPs is rich with features like inheritance, polymorphism, encapsulation and overloading enabling developers to extract more from modern day programming languages like C#, it is equally important to understand when to use these features based on design principles. SOLID, is a set of 5 principles which when properly applied intend to guide a programmer … Continue reading SOLID : Single Responsibility Principle

Singleton using Lazy(T)

Singleton Design Pattern is probably the simplest and most straightforward design pattern. So instead of explaining further, let me get to the code. The whole idea behind the above implementation of Singleton is to make use of the Lazy(T) class provided by Framework 4.0 and provide a lazy initialized version of the pattern, in addition … Continue reading Singleton using Lazy(T)
