Clean Code with C#

Enhance your programming skills through code reviews, TDD and BDD implementation, and API design to overcome code inefficiency, redundancy, and other issues arising from bad code

Key Features

• Write code that seamlessly integrates with other systems while maintaining well-defined software boundaries
• Understand how coding principles and standards elevate software quality
• Learn how to avoid common errors while implementing concurrency or threading

Book Description

Traditionally associated with Windows desktop applications and game development, C# has expanded into web, cloud, and mobile development. However, despite its extensive coding features, professionals often encounter issues with efficiency, scalability, and maintainability due to poor code. Clean Code in C# guides you in identifying and resolving these problems using coding best practices.

This book starts by comparing good and bad code to emphasize the importance of coding standards, principles, and methodologies. It then covers code reviews, unit testing, and test-driven development, and addresses cross-cutting concerns. As you advance through the chapters, you’ll discover programming best practices for objects, data structures, exception handling, and other aspects of writing C# computer programs. You’ll also explore API design and code quality enhancement tools, while studying examples of poor coding practices to understand what to avoid.

By the end of this clean code book, you’ll have the developed the skills needed to apply industry-approved coding practices to write clean, readable, extendable, and maintainable C# code.

What you will learn

• Master the art of writing evolvable and adaptable code
• Implement the fail-pass-refactor methodology using a sample C# console application
• Develop custom C# exceptions that provide meaningful information
• Identify low-quality C# code in need of refactoring
• Improve code performance using profiling and refactoring tools
• Create efficient and bug-free code using functional programming techniques
• Write cross-platform code using MAUI
• Develop cloud-deployable microservices for versatile applications
