Overview of this book

The ability to develop web applications that are highly efficient but also easy to maintain has become imperative to many businesses. ASP.NET Core 2.0 is an open source framework from Microsoft, which makes it easy to build cross-platform web applications that are modern and dynamic. This book will take you through all of the essential concepts in ASP.NET Core 2.0, so you can learn how to build powerful web applications. The book starts with a brief introduction to the ASP.NET Core framework and the improvements made in the latest release, ASP.NET Core 2.0. You will then build, test, and debug your first web application very quickly. Once you understand the basic structure of ASP.NET Core 2.0 web applications, you'll dive deeper into more complex concepts and scenarios. Moving on, we'll explain how to take advantage of widely used frameworks such as Model View Controller and Entity Framework Core 2 and you'll learn how to secure your applications. Finally, we'll show you how to deploy and monitor your applications using Azure, AWS, and Docker. After reading the book, you'll be able to develop efficient and robust web applications in ASP.NET Core 2.0 that have high levels of customer satisfaction and adoption.

Working with WebSockets for real-time communication scenarios


At the end of the previous section, everything was working fully automated as expected. However, there is still some room for additional improvements.

As it is, the client side sends periodical requests to the server side to see if the email confirmation status has changed. This may lead to a lot of requests to see if there has been a status change or not.

Furthermore, the server side cannot inform the client side as soon as an email has been confirmed, since it has to wait for a client request to respond to.

In this section, you will learn about the concepts of WebSockets (https://docs.microsoft.com/en-us/aspnet/core/fundamentals/websockets), and how they will allow you to further optimize your client-side implementations.

WebSockets enables persistent two-way communication channels over TCP, which is especially interesting for applications that need to run real-time communication scenarios (chat, stock tickers, games, and more)...
