GitHub Copilot Agents with Visual Studio 2026 Made Easy: Debug, Test, Profile, Refactor, and Modernize C# and .NET Applications with AI-Assisted Devel

By Voon Kiong Liew

GitHub Copilot Agents with Visual Studio 2026 Made Easy is a practical beginner-to-early-intermediate guide for developers, students, educators, and .NET learners who want to use AI-assisted development effectively inside Visual Studio 2026.

This book is written in the clear "Made Easy" style. It is designed for readers who want step-by-step explanations, practical examples, useful prompts, guided workflows, and simple C#/.NET examples that show how GitHub Copilot can support real software development tasks.

As programming tools become more intelligent, developers are no longer limited to writing code manually line by line. With GitHub Copilot, Copilot Chat, inline suggestions, slash-command workflows, context-aware assistance, and agent-style development, you can explain unfamiliar code, debug errors, generate unit tests, improve performance, refactor messy methods, review security risks, modernize older applications, and build C# projects more efficiently.

This book teaches you how to use Copilot as a development assistant, not as a replacement for understanding. You will learn how to write better prompts, use common Copilot workflows, review AI-generated code, test suggestions, and make responsible programming decisions.

Inside this book, you will learn how to:

Use GitHub Copilot effectively in Visual Studio 2026Understand Copilot Chat, inline suggestions, and agent-style workflowsUse practical Copilot commands and workflow patterns for common development tasksWrite better prompts for coding, debugging, testing, refactoring, and modernizationUse Copilot to explain existing C# codeFix common C# errors with AI assistanceGenerate unit tests with xUnit and MSTestImprove code quality, naming, validation, and maintainabilityOptimize LINQ and Entity Framework queriesModernize older .NET and Windows Forms applicationsUse Copilot with ASP.NET Core APIsReview code for security, validation, sensitive data exposure, and error handlingCreate custom Copilot agent-style workflowsUse Copilot responsibly in education and professional developmentBuild a complete AI-assisted C# Sales Order Calculator project

Use the appendix as a practical reference for Copilot commands, chat workflows, agent-style tasks, debugging, testing, refactoring, documentation, modernization, and safe review of AI-generated code

This book is especially suitable for students, self-learners, coding instructors, beginner developers, Windows Forms developers, ASP.NET Core learners, and early-intermediate .NET programmers who want a practical introduction to AI-assisted development in Visual Studio.

Please note that this book is not intended to be a complete advanced reference manual for every GitHub Copilot command, enterprise administration setting, internal configuration option, or large-scale corporate deployment scenario. Instead, it focuses on practical learning, guided examples, and developer workflows that help readers understand how to use Copilot productively and responsibly.

Whether you are learning C#, teaching programming, maintaining older .NET applications, building ASP.NET Core APIs, or exploring AI-assisted software development for the first time, this book will help you become more productive, more confident, and more systematic in modern C# and .NET development.

Learn how to debug, test, profile, refactor, modernize, and build better C# and .NET applications with GitHub Copilot Agents and Visual Studio 2026.
