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.

Learn the best ways to exploit the networking APIs in the .NET Framework—and deliver greater flexibility, interoperability, and power to your network applications. Three network programming specialists from Microsoft demonstrate how to use the System.Net namespace, which contains the core classes for network development, across a range of scenarios—from writing your first socket-based application to developing high performance N-tier Web applications. Whether you’re a Win32-based network programmer moving to the .NET Framework or you’re an XML Web Services or .NET Remoting developer looking for a better understanding of how these technologies relate to the network, this singular reference delivers the code and instruction you need. Discover how to: Use serialization techniques—binary, XML, and SOAP—to package complex data Enable concurrent programming—and increase application flexibility—with threads and asynchronous I/O Resolve URIs without writing protocol-specific code Communicate over IP networks using DNS, IPv4, and IPv6 Learn core to advanced socket programming techniques for both client and server operations Employ the .NET Web-related classes to retrieve HTTP content—proxy servers, cookies, credentials, and more Fine?tune XML Web services in your network programs and customize the underlying HTTP protocol for optimal efficiency Write a .NET Remoting custom channel to communicate over any data transmission medium Utilize code access security, encryption technology, and HTTP authentication techniques Boost application performance and scalability by streamlining resources

On its own, C# simplifies network programming. Combine it with the precise instruction found in C# Network Programming, and you'll find that building network applications is easier and quicker than ever. This book helps newcomers get started with a look at the basics of network programming as they relate to C#, including the language's network classes, the Winsock interface, and DNS resolution. Spend as much time here as you need, then dig into the core topics of the network layer. You'll learn to make sockets connections via TCP and "connectionless" connections via UDP. You'll also discover just how much help C# gives you with some of your toughest chores, such as asynchronous socket programming, multithreading, and multicasting. Network-layer techniques are just a means to an end, of course, and so this book keeps going, providing a series of detailed application-layer programming examples that show you how to work with real protocols and real network environments to build and implement a variety of applications. Use SNMP to manage network devices, SMTP to communicate with remote mail servers, and HTTP to Web-enable your applications. And use classes native to C# to query and modify Active Directory entries. Rounding it all out is plenty of advanced coverage to push your C# network programming skills to the limit. For example, you'll learn two ways to share application methods across the network: using Web services and remoting. You'll also master the security features intrinsic to C# and .NET--features that stand to benefit all of your programming projects.
