Programming .NET Web Services
Web services are poised to become a key technology for a
wide range of Internet-enabled applications, spanning
everything from straight B2B systems to mobile devices and
proprietary in-house software. While there are several
tools and platforms that can be used for building web
services, developers are finding a powerful tool
in
Microsoft's .NET Framework and Visual Studio .NET. Designed
from scratch to support the development of web services, the
.NET Framework simplifies the process--programmers find that
tasks that took an hour using the SOAP Toolkit take just
minutes.
Programming .NET Web Services is a comprehensive tutorial
that teaches you the skills needed to develop web services
hosted on the .NET platform. Written for experienced
programmers, this book takes you beyond the obvious
functionality of ASP.NET or Visual Studio .NET to give you a
solid foundation in the building blocks of web services, and
leads you step-by-step through the process of creating your
own.
Beginning with a close look at the underlying technologies
of web services, including the benefits and limitations,
Programming .NET Web Services discusses the unique features
of the .NET Framework that make creating web services
easier, including the Common Language Runtime (CLR) and the
namespaces used in .NET programming. Filled with numerous
code examples using the C# language, the book leads you
through some of the more challenging issues of web services
development, including the use of proxies, marshalling of
complex data types, state management, security, performance
tuning and cross-platform implementation. The book also
covers:
Creating and publishing your first web service
The UDDI project, tModels and what they mean for web service
publishers
Securing web service applications
Written for programmers who are familiar with the .NET
Framework and interested in building industrial-strength web
services, Programming .NET Web Services is full of practical
information and good old-fashioned advice.
