Structure of .NET Framework Version 3.0

The Microsoft .NET Framework version 3.0 (formerly known as WinFX) is the new managed-code programming model for Windows. It combines the power of .NET Framework 2.0 with new technologies for building applications that have a visually compelling user experience, seamless communication across technology boundaries, and support for a wide range of business processes. Microsoft plans to ship .NET Framework 3.0 as part of Windows Vista. At the same time, Microsoft will make .NET Framework available for Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1.

The following table lists some of the technologies included with .NET Framework 3.0.



Windows Presentation Foundation (WPF, formerly code-named “Avalon”)

Provides classes for building next-generation smart-client applications that combine UI, documents, and media.

Windows Communication Foundation (WCF, formerly code-named “Indigo”)

Offers a unified programming model and runtime for building service-oriented applications.

Windows Workflow Foundation (WWF)

Offers a programming model, engine, and tools to build workflow-enabled applications that model business processes.

Windows CardSpace (formerly code-named “InfoCard”)

Provides a technology for simplifying and improving the safety of working online with personal identity information.

Microsoft .NET Framework 2.0

Enables productively building Windows and Web-based applications.

All of the classes that represent the new components (WPF, WF, WCF, and CardSpace) are part of the System namespace. The core classes of the .NET platform, such as the common language runtime (CLR) and base class libraries (BCL) remain as they are in .NET Framework 2.0.

The following diagram illustrates the structure of .NET Framework 3.0.
