Pro C# 5.0 and the .NET 4.5 Framework

This new edition of Pro C# 5.0 and the .NET 4.5 Platform has been completely revised and rewritten to reflect the latest changes to the C# language specification and new advances in the .NET Framework. 

Beginning ASP.NET Security

You may know ASP.NET, but if you don't understand how to secure your applications, you need this book. This vital guide explores the often-overlooked topic of teaching programmers how to design ASP.NET Web applications so as to prevent online thefts and security breaches.

Creating Discovery Proxy part 1

All the previous posts in WCF have relied on a well known UDP multicast endpoint for discovery. The port and multicast address are specified by the WS-Discovery protocol documentation. The utilization of this multicast discovery is referred to as ad hoc discovery. Ad hoc discovery is limited to recognizing only services on the same subnet. Managed discovery allows you to locate services no matter where they are, as long as they are registered with a discovery proxy.

Pro C# 2010 and the .NET 4 Platform

The first edition of this book was released at the 2001 Tech-Ed conference in Atlanta, Georgia. At that time, the .NET platform was still a beta product, and in many ways, so was this book. This is not to say that the early editions of this text did not have merit—after all, the book was a 2002 Jolt Award finalist and it won the 2003 Referenceware Excellence Award. However, over the years that author Andrew Troelsen spent working with the common language runtime (CLR), he gained a much deeper understanding of the .NET platform and the subtleties of the C# programming language, and he feels that this fifth edition of the book is as close to a “final release” as he’s come yet.

Announcements

Most chat applications notify you when other users sign in. This application can discover other users but it would be better if we were notified when other users sign in. Discovery supports this feature with announcements

Metadata Extensions

From last article Ad hoc Discovery . When YallaTech discovered other chat instances all we knew about them was the Uri of the service endpoint. So her chat window shows a chat with the host machine name. besho, on the other hand, knew that the chat message came from YallaTech because the chat message included her name. In this article we will learn how we can extend the metadata used in WS-Discovery to supply additional information (such as the username used for the chat session).

Ad hoc Discovery

In this article we will add an ad hoc discovery mechanism to the DiscoveryChat program using System.ServiceModel.Discovery, an implementation of the WS-Discovery protocol.  In order for a service to be discoverable in an ad hoc manner it needs to respond to incoming probe messages. Ad hoc discovery implies that these probe messages come in through a well known port over UDP multicast.
