Refactoring with C#

Part 1: Refactoring with C# in Visual Studio

In the first part of the book, we’ll discuss the nature of technical debt, code smells, and refactoring. We’ll focus on the mechanical process of refactoring C# code in Visual Studio.

Throughout this part, you’ll learn how to safely alter the form of your code without changing its functionality. We’ll cover high-level concepts and then walk through refactoring individual lines of code. After this, we’ll zoom out to refactor entire methods and see how they interact with each other. Finally, we’ll look at some object-oriented approaches to refactoring that can help truly reshape your code by altering how classes interact with each other.

This part of the book can either be read as a traditional book or used as a step-by-step tutorial for refactoring the starting code found in each chapter.

This part contains the following chapters:

  • Chapter 1, Technical Debt, Code Smells, and Refactoring
  • Chapter 2, Introduction to Refactoring
  • Chapter 3, Refactoring Code Flow and Iteration
  • Chapter 4, Refactoring at the Method Level
  • Chapter 5, Object-Oriented Refactoring

Key benefits

  • Apply a wide range of refactoring techniques using the latest tools and features of C#
  • Discover ways to safely improve your code using tests, Roslyn analyzers, and AI assistance
  • Find ways of communicating technical debt and improving your code in agile and enterprise settings
  • Purchase of the print or Kindle book includes a free PDF eBook

Description

Software projects start as brand-new greenfield projects, but invariably become muddied in technical debt far sooner than you’d expect. In Refactoring with C#, you'll explore what technical debt is and how it arises before walking through the process of safely refactoring C# code using modern tooling in Visual Studio and more recent C# language features using C# 12 and .NET 8. This book, written by a Microsoft MVP, will guide you through the process of refactoring safely through advanced unit testing with XUnit and libraries like Moq, Snapper, and Scientist .NET. You'll explore maintainable code through SOLID principles and defensive coding techniques made possible in newer versions of C#. You'll also find out how to run code analysis and write custom Roslyn analyzers to detect and resolve issues unique to your code. The nature of coding is changing, and you'll explore how to use AI with the GitHub Copilot Chat to refactor, test, document, and generate code before ending with a discussion about communicating technical debt to leadership and getting organizational buy-in to refactor your code in enterprise organizations and in agile teams. By the end of this book, you'll understand the nature of refactoring and see how you can safely, effectively, and repeatably pay down the technical debt in your application while adding value to your business.

Who is this book for?

This book is for any developer familiar with C# who wants to improve the code they work with on a day-to-day basis. While this book will be most beneficial to new developers with only a year or two of experience, even senior engineers and engineering managers can make the most of this book by exploring not just the process of refactoring, but advanced techniques with libraries like Moq, Snapper, Scientist .NET, and writing custom Roslyn analyzers.

What you will learn

  • Understand technical debt, its causes and effects, and ways to prevent it
  • Explore different ways of refactoring classes, methods, and lines of code
  • Discover how to write effective unit tests supported by libraries such as Moq
  • Understand SOLID principles and factors that lead to maintainable code
  • Use AI to analyze, improve, and test code with the GitHub Copilot Chat
  • Apply code analysis and custom Roslyn analyzers to ensure that code stays clean
  • Communicate tech debt and code standards successfully in agile teams

I received an early copy of Matt Eland's book and was able to read most of it over the last two weeks. I recommend this book to .NET developers with all levels of experience.If you're new to .NET, the early chapters provide all the basics of different refactoring techniques. The TDD chapter is also a great kick-start to the test-first approach to coding with .NET.If you're an experienced .NET developer, you may skim through some of the early chapters (and still pick up some useful information - always be learning). The chapter on leveraging AI for refactoring is timely, and Matt's AI knowledge really shines through here. The chapters on Roslyn will appeal to newbies and seasoned developers alike. Everyone should try creating their own refactorings with the Roslyn APIs. It's a great way to help understand the compiler that most .NET devs take for granted.This book has a wonderful balance of coding instructions and patters & practices guidance.

It isn’t just that this book addresses every aspect of rehabilitating a .NET codebase. Matt succinctly informs us how to communicate on, plan for and tackle tech debt in any .NET enterprise application. Developers of any level of experience will find value here. If unstable, unreliable and unreadable code is a crime, then Matt Eland is the programming Batman!

If you are looking to hone your craft and level up your development skills with C#, or you are recently out of a coding bootcamp or graduating with a college degree and want to learn skills and concepts to set yourself apart from others, this book should be on your "must haves" list. This book could also be the thing that helps you as you move from a "junior" to a "senior" level developer.Matt has organized this book well, taking you through a system where there are problems that mimic the problems you will encounter in the real world. You then get to see how to use the default tools to refactor your code, as well as gain an understanding as to why the refactoring has made your code better. This system is consistent through the book, so you'll want to take it from the ground up and follow through to see the full transition of the software.There are many things that trip developers up on a day-to-day basis and they are captured in this book, whether they are basic problems or complex issues. Seasoned developers may find a couple of the concepts all too familiar as you walk through the book but there are some really great additional tools that even veterans may not have heard about that you will want to put into your toolbox.As a trainer of developers, I will be recommending this book heavily to my students, both for the content it offers and the overall comprehension it will provide on some of the tricky pitfalls developers encounter.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter.
