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.

Adding the SignalR libraries

Next, we need to add the SignalR package files to our project.

At the time of writing, the package for ASP.NET Core SignalR could not be found when browsing in the NuGet Package Manager, so we'll use the Package Manager Console to add the packages needed.

  1. Go to Tools | NuGet Package Manager | Package Manager Console:
  1. In the console window type the following command and hit enter:
Install-Package Microsoft.AspnetCore.SignalR -Version 1.0.0-alpha2-final

You should see a few response lines showing the items that were Successfully installed.

We also need the SignalR client JavaScript library for our project. For this we'll use an npm command.


npm is a package manager, like NuGet, but for JavaScript. Feel free to check it out at

  1. In the console window type the following command and hit enter:
npm install @aspnet/signalr-client

This will download a host of js files to a node_modules folder within your project's root directory. The output may show some...
