Simple and Efficient Programming with C#
Description
Each chapter opens with an introduction and original application written in C# 9 for you to jump into coding. From there, you are guided through an expected output and taught best practices along the way. Author Vaskaran Sarcar emphasizes extending and maintaining the same program and he demonstrates examples for different scenarios to make your program more efficient and effective.
This book is divided into four parts. The first part starts with a detailed discussion of polymorphism. It then shows you how to make proper use of abstract classes and interfaces, and you will know which technique to use for a specific scenario. Discussions on code comments teach you how to use them effectively, and why you need to be careful with code comments.
In the second part you will learn six design principles, including SOLID and DRY principles. These are the foundation of well-known design patterns and they establish practices for developing software with considerations for maintaining and extending as a project grows.
The third part takes you through the methods to make efficient applications. You will learn the common use of factories to separate code from its opposite and the alternative of inheritance using object composition and wrappers. This part also demonstrates the use of template methods, hooks, and facades in programming. Hints show you how professional coders develop an enterprise application.
In the fourth and final part you will learn about effective memory management techniques by preventing leaks in your application and the use and misuse of design patterns. This part also discusses how to decide between a static method and an instance method and other techniques, in brief.
After reading this book, you will be able to implement best practices to make your programs more effective and reliable.

Chapter 3: Abstract Class, or Interface?Chapter Goal: In this chapter, we do not compare the basic differences between an abstract class or an interface. Instead, we discuss the code segments where you can use either of them, but the compiler does not raise any issue. Then we will analyze how to write efficient code using both these techniques for some specific scenarios.

Chapter 5: The SOLID Principle(s)
Chapter Goal: This chapter explains the Single Responsibility Principle( SRP), Open/Closed Principle (OCP), Liscov Substitution Principle (LSP), Interface Segregation Principle (ISP),and Dependency Inversion Principle (DIP) principles (with and without ) with code examples.
