SOLID-Liskov Substitution Principle (LSP) Real-Time Example in C#

The SOLID Principles are the design principles that enable us to manage several software design problems. These principles provide us with ways to move from tightly coupled code to loosely coupled and encapsulated real business needs properly. Also readable, adaptable, and scalable code. The SOLID Principles  guide developers as they write readable, adaptable, and scalable code or design an application. The SOLID Principles can be applied to any OOP program. The SOLID Principles were developed by computer science instructor and author Robert C. Martin. Now, SOLID principles have also been adopted in both agile development and adaptive software development. The 5 principles of SOLID are: 1.       Single Responsibility Principle (SRP) 2.       Open-Closed Principle (OCP) 3.       Liskov Substitution Principle (LSP) 4.       Interface Segregation Principle (ISP) 5. ...
