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 codeKey FeaturesWrite code that cleanly integrates with other systems while maintaining well-defined software boundariesUnderstand how coding principles and standards enhance software qualityLearn how to avoid common errors while implementing concurrency or threadingBook DescriptionTraditionally 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 learnWrite code that allows software to be modified and adapted over timeImplement the fail-pass-refactor methodology using a sample C# console applicationAddress cross-cutting concerns with the help of software design patternsWrite custom C# exceptions that provide meaningful informationIdentify poor quality C# code that needs to be refactoredSecure APIs with API keys and protect data using Azure Key VaultImprove your code's performance by using tools for profiling and refactoringWho this book is forThis coding book is for C# developers, team leads, senior software engineers, and software architects who want to improve the efficiency of their legacy systems.
