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.

  1. What are the valid values for the CachePolicy property of the WebRequest class, and where can they be found?
  2. What is the method used to associate the custom sub-classes of the WebRequest class with requests to the associated protocol for that custom sub-class?
  3. What property is used to associate multiple requests to the same connection in the .NET connection pool?
  4. What are the four preregistered protocols for which the WebRequest class is configured to return a valid sub-class from the Create(uri) method?
  5. What is the difference between BeginGetRequestStream(), GetRequestStreamAsync(), and GetRequestStream()?
  6. Name some of the ways the HttpWebRequest class differs from the default behavior of the WebRequest class?
  7. Why is it important to always leverage ConnectionGroupName whenever possible?
