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.

The Open Systems Interconnection network stack

There are several steps in the process of sending or receiving a resource from a remote source over a network, and each of those steps has been deeply considered by the network engineers tasked with executing them. In this section, we'll look at who those network engineers were, and how they defined a general pattern for implementing each step in that process. This section will be all about the OSI, and how that specification defines the network stack of a given network device.

What exactly is the Open Systems Interconnection?

In order to talk about communication protocols, we need to understand how each protocol fits into the larger picture of network connectivity, and to...
