The SOLID principles in Dotnet C#

SOLID principles

This repository contains the SOLID principles details and code examples written in Dotnet C#.

Definition

SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible, and maintainable.

👆 Wikipedia documentation

The SOLID principles are:

[S] Single responsibility principle

There should never be more than one reason for a class to change. In other words, every class should have only one responsibility.

Code example and documentation 📄

[O] Open–closed principle

Software entities should be open for extension, but closed for modification.

Code example and documentation 📄

[L] Liskov substitution principle

Functions that use pointers or references to base classes must be able to use objects of derived classes without knowing it. See also design by contract.

Code example and documentation 📄

[I] Interface segregation principle

Many client-specific interfaces are better than one general-purpose interface.

Code example and documentation 📄

[D] Dependency inversion principle

Depend upon abstractions, not concretions.
