Directory Services encapsulate and expose objects within a network, offering a unified way of accessing different types of data. Of particular interest on the Windows platform is the Active Directory, which supplies powerful and flexible methods for managing users, servers, and resources in a single information store that is globally accessible throughout an enterprise. Knowing how and when to use a Directory Service effectively will enable you to develop applications that store infrastructure information safely, as well as perform management or administrative tasks.This book looks at the .NET Framework's support for programming Directory Services, and in particular, the Active Directory. The reader will learn how to create applications to view, search, or manage directory entries such as users as well as physical resources such as printers. The book is divided into two sections. The first covers some background information about directory services, Active Directory and ADSI, and then looks in detail at the support provided by the .NET Framework in the System.DirectoryServices namespace for working with directory services. The second part looks at some of the most important specific tasks faced by developers and administrators, and shows how to achieve these through C# code.This will be the only book dedicated to programming directory services using the .NET Framework. This topic isn't well covered in any of the more general books, and anecdotal evidence from the .NET mailing lists suggests that there's a lot of demand for information on the topic.

Networking is one of the core tasks of enterprise-level programming, and for the programmer familiar with the C# language this book should provide the information to put network programming at the heart of their .NET applications. Prior knowledge of network programming is not assumed, but the reader already familiar with networking from another environment will find the pace quick enough for the book to still prove valuable. This book should give the reader: an understanding of the general concepts of networking; information about network programming in .NET with C#; skills to build network-based applications in .NET; and the confidence to use the classes shipped with .NET to implement your own application-level protocols. The book begins with an overview of the most important background material, such as the architecture of physical networks, network protocols, the OSI model, streams in .NET, and the classes provided to facilitate access to streams such as StreamReader and StreamWriter. Then it moves onto sockets programming, with an introduction to the concept of sockets, and full coverage of using sockets in .NET. It looks at TCP, UDP, and using multicast sockets in .NET and at application-level protocols built on top of these layers, such as SMTP and FTP. The next stop is Internet programming, with a look at HTTP, the underlying protocol of the Internet, and e-mail protocols. The book finishes with an exploration of how to secure network communications in .NET - encrypting network traffic, certificates and SSL, authenticating and authorizing users with NTLM and Kerberos.
