Modern Web Development with ASP.NET Core 3 - Second Edition

By: Ricardo Peres

Overview of this book

ASP.NET has been the preferred choice of web developers for a long time. With ASP.NET Core 3, Microsoft has made internal changes to the framework along with introducing new additions that will change the way you approach web development. This second edition has been thoroughly updated to help you make the most of the latest features in the framework, right from gRPC and conventions to Blazor, which has a new chapter dedicated to it. You’ll begin with an overview of the essential topics, exploring the Model-View-Controller (MVC) pattern, various platforms, dependencies, and frameworks. Next, you’ll learn how to set up and configure the MVC environment, before delving into advanced routing options. As you advance, you’ll get to grips with controllers and actions to process requests, and later understand how to create HTML inputs for models. Moving on, you'll discover the essential aspects of syntax and processes when working with Razor. You'll also get up to speed with client-side development and explore the testing, logging, scalability, and security aspects of ASP.NET Core. Finally, you'll learn how to deploy ASP.NET Core to several environments, such as Azure, Amazon Web Services (AWS), and Docker. By the end of the book, you’ll be well versed in development in ASP.NET Core and will have a deep understanding of how to interact with the framework and work cross-platform.

Real-Time Communication

In this chapter, we will learn about MicrosoftSignalR, which is a library fordoingreal-time communication between the client and the server. It allows the server to call the client of its own initiative, not as a result of a request. It builds on well-known technologies such as AJAX, WebSockets, and server-sent events, but in a transparent manner. You do not need to know what it's using—it basically just works, regardless of the browser you have. It also supports quite a lot of browsers, including mobile phones. Let's explore this technology and see what it has to offer—essentially, the following:

  • Setting up SignalR
  • Sending messages from the client to the server
  • Broadcasting messages from the server to all/some clients
  • Sending messages from outside a hub

After reading this chapter, you will learn how to communicate...
