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.

DNS and Resource Location

The last chapter was spent dissecting networks to such a degree that most readers will likely never think about them again. In this chapter, we'll take those concepts and look at their real-world implementations. We'll start with a look at how the problem of resource allocation is solved at the scale of the internet. Distributing resources is useless without being able to access them from across your network, and this chapter will introduce you to the systems and standards that make doing so possible. As we investigate these topics, we'll finally get our hands dirty with some code. Throughout this chapter, we'll look at software examples to get you familiar with leveraging the tools available with the .NET Core framework.

The following topics will be covered in this chapter:

  • How data and services are exposed and made available on...
