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.

Chapter 5. ASP.NET SignalR Chat Application

Imagine having the ability to have your server-side code push data to your web page in real time, without the user needing to refresh the page. As they say, there are many ways to skin a cat, but the ASP.NET SignalR library provides developers with a simplified method to add real-time web functionality to applications.

To showcase the capabilities of SignalR, we'll build a simple ASP.NET Core SignalR chat application. This will include the use of NuGet and Node Package Manager (npm) to add the required package files to the project.

In this chapter, we will look into the following:

  • Overall project layout
  • Setting up the project
  • Adding the SignalR libraries
  • Building the server
  • Creating a client
  • Solution overview
  • Running the application

Let's dive in.
