Synopsis

Develop your programming skills by exploring essential topics such as code reviews, implementing TDD and BDD, and designing APIs to overcome code inefficiency, redundancy, and other problems arising from bad code

Key Features

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

Book Description

Traditionally associated with developing Windows desktop applications and games, C# is now used in a wide variety of domains, such as web and cloud apps, and has become increasingly popular for mobile development. Despite its extensive coding features, professionals experience problems related to efficiency, scalability, and maintainability because of bad code. Clean Code in C# will help you identify these problems and solve them using coding best practices.

The book starts with a comparison of good and bad code, helping you understand the importance of coding standards, principles, and methodologies. You'll then get to grips with code reviews and their role in improving your code while ensuring that you adhere to industry-recognized coding standards. This C# book covers unit testing, delves into test-driven development, and addresses cross-cutting concerns. You'll explore good programming practices for objects, data structures, exception handling, and other aspects of writing C# computer programs. Once you've studied API design and discovered tools for improving code quality, you'll look at examples of bad code and understand which coding practices you should avoid.

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

What you will learn

• Write code that allows software to be modified and adapted over time
• Implement the fail-pass-refactor methodology using a sample C# console application
• Address cross-cutting concerns with the help of software design patterns
• Write custom C# exceptions that provide meaningful information
• Identify poor quality C# code that needs to be refactored
• Secure APIs with API keys and protect data using Azure Key Vault
• Improve your code's performance by using tools for profiling and refactoring

Who this book is for
