Encapsulated with sufficient context

C# and .NET Core makes network programming the enjoyable experience it should be. This book will get you started with the basics of network programming as they relate to C#. We will then dig into the core topics of the network layer. You'll also learn to make sockets connections as well and develop practical client-side applications in this book.
