Solid Principles in CSharp

Introduction
SOLID principles are essential guidelines for writing clean, maintainable, and extensible C# code. This article will discuss each SOLID principle and provide examples in C#.

Single Responsibility Principle

The Single Responsibility Principle (SRP) states that a class should have only one reason to change. This principle ensures that a class is responsible for only one thing and promotes code readability and maintainability.

Open/Closed Principle

The Open/Closed Principle (OCP) states that a class should be open for extension but closed for modification. This principle promotes code extensibility and maintainability.

 Liskov Substitution Principle

The Liskov Substitution Principle (LSP) is a principle in object-oriented programming that states that child classes or subclasses must be substitutable for their parent classes or superclasses. In other words, the child class must be able to replace the parent class without affecting the correctness of the program.

Interface Segregation Principle

The Interface Segregation Principle states that Clients should not be forced to implement any methods they don’t use. Rather than one fat interface, numerous little interfaces are preferred based on groups of methods, with each interface serving one submodule.

Dependency Inversion Principle

The Dependency Inversion Principle (DIP) states that high-level modules/classes should not depend on low-level modules/classes. Both should depend upon abstractions. Secondly, abstractions should not depend upon details. Details should depend upon abstractions.
