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.

In this chapter, we examined the primary characteristics network engineers identified as necessary to make networks viable. We considered the trade-off of usability for routing hardware versus readability for humans when defining a standard syntax for network addressing. With that consideration in mind, we looked at how the work of the telecom engineers of previous generations contributed hugely to the solutions that were ultimately standardized on all modern networks today.

Within that context, we looked at how IP addresses are used by network hardware to locate resources, and how the DNS facilitates the more memorable, human-readable addressing schemes of URLs and URIs. We learned how those domain names are explicitly mapped to their underlying IP addresses by implementing a domain name server of our own, using the hosts file of our operating system. Using the sandbox...
