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 took an extensive tour of the motivations for, and use cases of, data caches in a distributed network application. We started by exploring some common business and design problems that would likely reap the benefits of a caching strategy. In doing so, we identified some of the basic considerations you can make when determining if the complexity of introducing a cache management system is the right decision for your application. Then, we looked at exactly which benefits could be gained from caching, and precisely how caching can provide them.

Once we learned why we might use a cache, we looked at some of the common problems that must be solved for when implementing a cache. First, we tackled the tactics of pre-caching data and caching results on demand. Then, we looked at how to determine which data or resources should be cache. We learned about establishing...
