Overview of this book

With the rise in the number of tools and technologies available today, developers and architects are always exploring ways to create better and smarter solutions. Before, the differences between target platforms was a major roadblock, but that's not the case now. .NET Core 2.0 By Example will take you on an exciting journey to building better software. This book provides fresh and relevant content to .NET Core 2.0 in a succinct format that’s enjoyable to read. It also delivers concepts, along with the implications, design decisions, and potential pitfalls you might face when targeting Linux and Windows systems, in a logical and simple way. With the .NET framework at its center, the book comprises of five varied projects: a multiplayer Tic-tac-toe game; a real-time chat application, Let'sChat; a chatbot; a microservice-based buying-selling application; and a movie booking application. You will start each chapter with a high-level overview of the content, followed by the above example applications described in detail. By the end of each chapter, you will not only be proficient with the concepts, but you’ll also have created a tangible component in the application. By the end of the book, you will have built five solid projects using all the tools and support provided by the .NET Core 2.0 framework.

Now that we have the authentication module in place, a user can log in to our Let's Chat web application using Facebook. We still need to develop the Chat module so that the user can see their friends online and chat with them. In this section, we will develop the Chat hub module using SignalR. We have already developed a Tic-Tac-Toe game using SignalR. Hence, we are already familiar with how to develop a SignalR hub and get the communication going back and forth between clients and server, so this should be relatively easier for us. On the client side, we will make use of Razor pages. ASP.NET Core 2.0 introduced a new feature called Razor pages, which makes the coding of page-focused scenarios much easier. If you have worked on earlier versions of ASP.NET, you will have seen or heard about ASP.NET Web forms (.aspx) applications, which had web forms at the heart of development. This is more or less on the same lines in the MVC world and makes it really productive to develop...
