The publication covers the full cycle of creating quality code: from variable naming to application architecture design. You will learn:

• How to apply SOLID principles in C# to create flexible and loosely coupled classes.
• Techniques for refactoring legacy code using .NET capabilities (LINQ, async/await, Generics).
• Rules for writing unit tests (unit tests) with xUnit/NUnit and integration tests for ASP.NET Core.
• How to conduct code review and implement coding standards in a team.
• Working with exceptions, logging, and error handling in .NET applications.

Who is this book for?

• Junior developers who want to avoid common mistakes and learn to write code that is understandable to colleagues.
• Middle developers seeking to deepen their knowledge in architecture and refactoring.
• Team Leads looking for practical advice on setting up code review processes and implementing best practices in the team.

What will you learn by reading this book?

• How to avoid code smells and transform chaotic code into clean architecture.
• Why comments are often harmful, and how to make code self-documenting.
• How to properly design classes, interfaces, and dependencies in .NET.
• Real-world refactoring examples: from bad code to clean code with step-by-step explanations.
• How testing helps maintain code cleanliness and prevent regressions.

The book is written in simple and clear language, with an emphasis on practice. All code examples are available for download and tested under .NET 8. If you want to stop spending hours debugging someone else's (or your own) code — this book is for you.
