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

To follow this chapter, you'll need to have either Visual Studio Code, or Visual Studio Community Edition. Both are free downloads available at the Visual Studio website, at https://visualstudio.microsoft.com/.

Check out the following video to see the code in action: http://bit.ly/2HVSHad

We'll also be using the .NET Core command-line interface (CLI). This will give us access to a series of programs we can call directly from the command prompt. To follow along, you'll need to make sure you have the .NET Core SDK installed locally, which can be downloaded from https://www.microsoft.com/net/download.
