What's New in the .NET Framework

The .NET Framework can also be fully extended by developers to create custom
classes and types. The functionality of the .NET Framework spans the server, the
workstation, and the Web. The four primary additions to the .NET Framework as of
version 3.0 are:

1. Windows Presentation Foundation (WPF)
   
2. Windows Communication Foundation (WCF)
   
3. Windows Workflow Foundation (WF)
   
4. CardSpace

Windows Presentation Foundation (WPF)

WPF is used to develop elaborate user interfaces like those that adorn
Windows Vista and managed advanced media streaming and integration. WPF is the a
complete revamp of Windows Forms so that user interface, graphic, and media
development is now designed around the .NET Framework.

Windows Communication Foundation (WCF)

WCF encompasses the ASP.NET Web Services and .NET remoting functionality that
was contained in the .NET Framework 2.0 as well as new communication
technologies.

Windows Workflow Foundation (WF)

WF is used to model complex workflow processes.
