.NET is more powerful-and more complex-than ever. As the ecosystem evolves, so do the expectations from developers. Mastering the tools and patterns of professional .NET development can be the difference between simply shipping code and delivering resilient, scalable software. Tools and Skills for .NET 10 is a practical guide to leveling up in today's .NET world, offering both hard technical skills and career strategies to help you thrive.Inside, you'll learn how to manage codebases with Git and implement debugging and memory analysis techniques that save hours of guesswork. The book also covers best practices for writing and maintaining documentation for your code, services, and APIs, which is crucial for team collaboration. You'll explore cryptography for securing data and concurrency for building responsive apps. Further chapters explore dependency injection, testing for performance and reliability, and packaging your apps in Docker containers.By the end of this book, you'll be equipped not only with technical skills but also with the confidence to apply them in real environments. Whether you're aiming for a promotion, switching jobs, or preparing for technical interviews, you'll have the skills and the language to present yourself as a capable, well-rounded .NET developer ready for anything the industry throws at you.
In this first chapter, the goals are understanding the tools and skills that you will learn in this book, setting up your development environment to use Visual Studio 2026, Visual Studio Code, or JetBrains Rider, and then setting up a database and projects to use in the rest of the chapters. Throughout this book, I will use the namesVisual Studio,VS Code, andRider to refer to these three code editors respectively.
I use the termmodern .NET to refer to .NET 10 and its predecessors like .NET 5, which derive from .NET Core. I use the termlegacy .NET to refer to .NET Framework, Mono, Xamarin, and .NET Standard. Modern .NET is a unification of those legacy platforms and standards.
Every chapter in this book introduces some tools and some skills, but some chapters are more focused on a particular tool or a particular skill.
This chapter covers the following topics:
The GitHub repository for this book has solutions using full application projects for all code tasks:https://github.com/markjprice/tools-skills-net10/.
After going to the GitHub repository, simply press the. (dot) key on your keyboard or change.com to.dev to change the repository into a live code editor based on VS Code using GitHub Codespaces. VS Code in a web browser is great to run alongside your chosen code editor as you work through the book’s coding tasks. You can compare your code to the solution code and easily copy and paste parts if needed.
