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.

Let's Chat web app – high-level design


In this section, we will look at the flowchart that we created and we will come up with granular modules to constitute the app using ASP.NET Core 2.0. We need to develop the following:

  • An authentication and authorization module that takes care of login and authentication of users
  • A registration module that takes care of user registration
  • A chat room page
  • A module that keeps track of all the logged in users and notifies the client chat room pages about the user joining and leaving
  • A user information module that keeps track of all the user information, such as display name, display picture, and so on
  • A chat hub module that enables a message to be broadcast from each user to the other online users

Sounds easy? Let's see how we can design and implement each of the preceding requirements using ASP.NET Core 2.0:

  • Authentication and authorization module: This is a core functionality and needed in most modern apps. It makes sense to use something that is already developed...
