Beginning-Intermediate user level

Apply skills and approaches to your programming to build a real-world application in C# 11 using the latest editions of Visual Studio, C#, and Microsoft .NET.

This revised edition is updated with C#11 and places more emphasis on the newly introduced top-level statements. Additionally, you will find useful techniques and an explanation of the differences between writing code in two different styles. It also covers the new templates introduced in .NET 6, along with usage of .NET 7 in Windows 10 to write code and generate output. 

Each chapter opens with an introduction and original application written in C# 11 so that you can jump right 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 five 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 teaches you to discern 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 walks you through 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.
Better handling of exceptions and null values is another integral part of professional programming, which the fourth part explores in detail. This will help you become a more professional programmer.
In the final part of the book, you will learn about effective memory management techniques and the use and misuse of design patterns. This part also briefly discusses how to decide between a static method and an instance method and other techniques.After reading this book, you will be able to implement best practices to make your programs more effective and reliable.

What Will You Learn

• Analyze alternative solutions before implementation by comparing pros and cons
• Make polymorphic code perform better
• Know the side effects of bad/redundant comments
• Understand the significance of the SOLID and DRY principles

Part I Basics 

Chapter 1:  Avoid Unnecessary Code Comments

Chapter Goal: To show you the proper use of comments. It also discusses the side-effects of bad/redundant comments.

No of pages: 5-10+

Chapter 2:  Use Polymorphism

Chapter Goal: To show why a polymorphic code can perform better.

No of pages    5-10+

Sub - Topics  

2.1 Initial Program: Demo 1

2.2 Output and Analysis

2.3  Making efficient programs: Demo 2

2.4  Analysis

2.5  Conclusion

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.

 No of pages: 10-15+

Chapter 4:  Static Method or Instance Method?

Chapter Goal: This chapter shows how to decide between a static method and an instance method. It shows the answer with supporting code examples.

No of pages: 5-10+

 

Part II Important Principles 

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.

No of pages    50+

Chapter 6:  The DRY Principle

Chapter Goal: In this chapter, you learn about the DRY principle and its importance by building applications in C#. DRY stands for DON'T REPEAT YOURSELF and is a basic principle of software development, aimed to reducing repetition of information. 

No of pages: 10-15+

Part III Make Flexible Applications 

Chapter 7:  Separate Changeable Code Using Factories

Chapter Goal: This chapter shows the common use of factories to separate the varying code from its opposite.
