Preface

There are programming books that are thousands of pages long that aim to be comprehensive references to .NET-based websites, web services, and desktop and mobile apps. This book is different.

This book is a step-by-step guide to learning modern technologies for building apps and services with .NET. It is concise and aims to be a brisk, fun read that is packed with practical hands-on walkthroughs of each topic.

The breadth of the overarching narrative comes at the cost of some depth, but you will find many signposts to explore further if you wish.

In my experience, the hardest part of learning a new technology is getting started. Once I have had the most important key concepts explained and seen some practical code in action, I then feel comfortable going deeper by exploring the official documentation on my own. You can feel confident experimenting on your own once you have seen how the basics work correctly.

This book is best for those who already know the fundamentals of C# and .NET, and programmers who have worked with C# in the past but feel left behind by the changes in the past few years.

If you already have experience with older versions of the C# language and .NET libraries, then I have covered what is new in modern .NET since 2016 in an online-only section at the end of Chapter 1, Introducing Apps and Services with .NET.

I will call out the most important aspects of app models and frameworks for building modern user interfaces and implementing services, so you can participate in conversations with colleagues about technology and architectural choices and get productive with their implementation fast.
