SOLID Principles in c#

SOLID is an acronym that stands for five fundamental principles of object-oriented design and development. These principles aim to promote cleaner, more robust, and updatable code for software development in object-oriented languages.

S - Single Responsibility Principle (SRP):
A class should have only one reason to change, meaning it should have only one job or responsibility.

O - Open/Closed Principle (OCP):
A class should be open for extension but closed for modification. You should be able to add new functionality without changing the existing code.

L - Liskov Substitution Principle (LSP):
Derived classes should be substitutable for their base classes. Any code that uses a base class should be able to work with a derived class without knowing the difference.

I - Interface Segregation Principle (ISP):
A client should not be forced to depend on interfaces it does not use. Instead of having a large, general interface, break it down into smaller, more specific interfaces.

D - Dependency Inversion Principle (DIP):
High-level modules should not depend on low-level modules. Both should depend on abstractions. Also, abstractions should not depend on details. Details should depend on abstractions.
