Overview of this book

.NET Core is a general purpose, modular, cross-platform, and open source implementation of .NET. With the latest release of .NET Core, many more APIs are expected to show up, which will make APIs consistent across .Net Framework, .NET Core, and Xamarin. This step-by-step guide will teach you the essential .NET Core and C# concepts with the help of real-world projects. The book starts with a brief introduction to the latest features of C# 7 and .NET Core 2.0 before moving on to explain how C# 7 can be implemented using the object-oriented paradigm. You'll learn to work with relational data using Entity Framework and see how to use ASP.NET Core practically. This book will show you how .NET Core allows the creations of cross-platform applications. You'll also learn about SignalR to add real-time functionality to your application. Then you will see how to use MongoDB and how to implement MongoDB into your applications. You'll learn about serverless computing and OAuth concepts, along with running ASP.NET Core applications with Docker Compose. This project-based guide uses practical applications to demonstrate these concepts. By the end of the book, you'll be proficient in developing applications using .NET Core 2.0.

Chapter 1. eBook Manager and Catalogue App

C# 7 is a fantastic release and is available in Visual Studio 2017. It introduces developers to a lot of powerful features, some of which were previously only available in other languages. The new features introduced in C# 7 allow developers to write less code and be more productive.

The features available are:

  • Tuples
  • Pattern matching
  • Out variables
  • Deconstruction
  • Local functions
  • Improvements to literals
  • Ref returns and locals
  • Generalized async and return types
  • Expression bodies for accessors, constructors, and finalizers
  • Throw expressions

This chapter will take you through some of these features, while the rest of the book will introduce you to some of the other features as we go along. In this chapter, we will create an eBookManager application. If you are like me, you have eBooks scattered all over your hard drives and some external drives as well. This application will provide a mechanism to bring all these various locations together into a Virtual Storage Space. The application is functional, but can be further enhanced to suit your needs. The scope for an application such as this is vast. You can download the source code from GitHub ( and follow it to see some of the new features of C# 7 in action.
