This
section is meant to give a brief introduction to WCF to help you
understand how WCF works with CardSpace. To gain a full understanding
of WCF would require a whole other book (for
example, Windows Communication Foundation Unleashed,
Sams Publishing, 2007).
Windows Communication Foundation
Most people??™s use of the Web is through a Web browser, browsing
between websites. Yet, online activities can be made richer
by the use of specialized applications that access online services
for speci?¬?c purposes but do not require downloading Web
pages and being con?¬?ned to the navigation models used by the
browser. A good example of a rich-client application could be
one used for banking, which gives a secure client application
experience, but is able to connect to an online service to access
an account. Custom applications built for employees to access
company data or perform daily tasks are another good use. Rich
clients allow us to directly access online data or save our data to
a secure location, which we can then access from any machine.
WCF supports these exact types of clients, making it easy for
developers to wire up the services needed to support the
applications, reliably and securely.
