Overview of this book

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.

FP and clean methods

C# is indeed considered an OOP language, but it also supports FP concepts. FP is a programming paradigm that treats computation as the evaluation of mathematical functions and avoids changing state and mutable data. In C#, you can leverage FP techniques to write clean and efficient functions, even within an OO context. Here’s how and why it’s important:

  • Immutability:
    • In FP, immutability is a fundamental concept. Immutability means that once an object is created, its state cannot be changed. You can use this concept in C# by creating immutable data structures or objects. Immutability can make your code cleaner and more predictable because you don’t need to worry about unexpected changes to your data.
  • Pure functions:
    • Pure functions are functions that have no side effects and always return the same output for the same input. Writing pure functions can make your code cleaner and more maintainable. You can write pure functions in C# by...
