Hands-On Network Programming with C# and .NET Core

By: Sean Burns

Overview of this book

The C# language and the .NET Core application framework provide the tools and patterns required to make the discipline of network programming as intuitive and enjoyable as any other aspect of C# programming. With the help of this book, you will discover how the C# language and the .NET Core framework make this possible. The book begins by introducing the core concepts of network programming, and what distinguishes this field of programming from other disciplines. After this, you will gain insights into concepts such as transport protocols, sockets and ports, and remote data streams, which will provide you with a holistic understanding of how network software fits into larger distributed systems. The book will also explore the intricacies of how network software is implemented in a more explicit context, by covering sockets, connection strategies such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), asynchronous processing, and threads. You will then be able to work through code examples for TCP servers, web APIs served over HTTP, and a Secure Shell (SSH) client. By the end of this book, you will have a good understanding of the Open Systems Interconnection (OSI) network stack, the various communication protocols for that stack, and the skills that are essential to implement those protocols using the C# programming language and the .NET Core framework.

Technical requirements

In this chapter, we'll be using sample applications available in the GitHub repository for the book here: https://github.com/PacktPublishing/Hands-On-Network-Programming-with-CSharp-and-.NET-Core/tree/master/Chapter 9.

We'll also be using each of the tools we leveraged in Chapter 8, Sockets and Ports. So, if you didn't take the time to install and start working with them before, I suggest you do so now. Specifically, I recommend installing Postman from here: https://www.getpostman.com/apps.

Alternatively, you can use the Insomnia REST client, which can be found here: https://insomnia.rest/.

And, while it's not going to be featured heavily in this chapter, since deployment options will fall outside the scope of this chapter, I would encourage you to use this opportunity to begin working with Docker. I'll point out opportunities to...
