Book Description
Web services are perhaps the most important feature of .NET development. They take componentization to a new level by allowing method calls to be made over the Internet or over an intranet using standard protocols such as HTTP and SOAP. This means that the calling application needs to know nothing about the internal implementation of the service - a web service built in C# on the .NET platform will (in theory) be indistinguishable from one built on Linux using Java.

The .NET Framework provides two ways to build web services - ASP.NET and .NET Remoting. Unlike most books on web services, this book covers both of these technologies in depth. .NET Remoting web services require a little extra effort to build, but they offer us greater flexibility. They allow us to use different encoding and channels, and they can be hosted in any application, not just IIS.

This book covers:

This book covers building web services and web service clients with both ASP.NET and .NET Remoting. We also look at the generic protocols used by web services - SOAP, WSDL, and we discuss discovering web services using Universal Description, Discovery and Integration (UDDI). Case studies illustrate the integration of web services into an application, and demonstrate how to create a custom channel sink to apply cryptography to a Remoting web service.

Web services are perhaps the most important feature of .NET development. They take componentization to a new level by allowing method calls to be made over the Internet or over an intranet using standard protocols such as HTTP and SOAP.

The .NET Framework provides two ways to build web services - ASP.NET and .NET Remoting. Unlike most books on web services, this book covers both of these technologies in depth. .NET Remoting web services require a little extra effort to build, but they offer us greater flexibility. They allow us to use different encoding and channels, and they can be hosted in any application, not just IIS. This book covers building web services and web service clients with both ASP.NET and .NET Remoting. It also looks at the generic protocols used by web services - SOAP, WSDL, and discusses discovering web services using Universal Description, Discovery and Integration (UDDI). Case studies illustrate the integration of web services into an application, and demonstrate how to create a custom channel sink to apply cryptography to a Remoting web service. This book is for anyone who is interested in building web services using the tools supplied with the .NET Framework, and wants to look at both of these technologies. Prior knowledge of C# and the .NET Framework is assumed.

Most Helpful Customer Reviews   7 of 8 people found the following review helpful: An OK introduction to web services, 23 Nov 2002 By  Thomas Paul (Plainview, NY USA) - See all my reviews       Building web services is generally a simple task in .NET. This book covers the two methods available to .NET developers to build web services, ASP.NET (referred to as XML Web Services) and .NET Remoting (a technology similar to RMI, although with more flexibility). There are several books that cover building web services with APS.NET but this book is rare in that it covers both technologies. If you aren't interested in .NET Remoting then you may want to look elsewhere. Overall, this book does a nice job of covering web services in .NET although it could have been better. The book suffers from the common problem of multiple authors, it tends to be repetitive. For example, the SOAP protocol. is explained in detail in chapter 2 , and then again in chapter 4. The chapter on web services security gives a good description of cryptography but doesn't discuss other issues of web service security. Although the book does discuss user authentication (although briefly) it does not discuss the problem of passing user credentials from one web service to another. At least half the book is case studies and examples so the actual content is not deep. The book is a fairly good basic introduction to web services. If you are new to web services and you are looking for a book that covers ASP.NET and .NET Remoting, you could do a lot worse than starting with this book.  Comment | Permalink | Was this review helpful to you?
