C# 7 and .NET Core 2.0 Blueprints

By: Dirk Strauss, Jas Rademeyer

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.

Entity Framework is an object-relational mapper (ORM). It maps your .NET code objects to relational database entities. As simple as that. Now, you don't have to concern yourself with scaffolding the required data-access code just to handle plain CRUD operations.

Thankfully, most of the raised concerns were addressed and the release of Entity Framework 4.0, together with .NET 4.0, put to bed a lot of the criticisms around the stability of the framework.
