Learning WCF
This easy-to-use introduction to Microsoft Windows
Communication Foundation (WCF) is ideal for developers who
want to learn to build services on a company network or as
part of an enterprise system. Built into Windows Vista and
Longhorn, and available for Windows XP and Windows 2003, WCF
provides a platform for service-oriented
architecture (SOA)
that enables secure and reliable communication among systems
within an organization or across the Internet. With WCF,
software developers can focus on their business applications
and not the plumbing required to connect them. Furthermore,
with WCF developers can learn a single programming API to
achieve results previously provided by ASMX, Enterprise
Services and .NET Remoting. Learning WCF removes the
complexity of using this platform by providing detailed
answers, explanations and code samples for the most common
questions asked by software developers.
Windows Communication Foundation (or WCF, formerly code name
"Indigo") provides a set of programming APIs that make it
easy to build and consume secure, reliable, and transacted
services. This platform removes the need for developers to
learn different technologies such as ASMX, Enterprise
Services and .NET Remoting, to distribute system
functionality on a corporate network or over the Internet.
The first truly service-oriented platform, WCF provides
innovations that decouple service design and development
from deployment and distribution - creating a more flexible
and agile environment. WCF also encapsulates all of the
latest web service standards for addressing, security,
reliability and more.
