.NET Framework 4 Client Profile available through Windows Update

.NET Framework now served through Windows Update

Beginning June 22, 2010 the .NET Framework 4 is available through WIndows Update to ease deployment.

The whole framework? No, only the "light" version, so called "Client Profile", which contains the features to develop a client application, including:

Common language runtime (CLR)


Windows Forms

Windows Presentation Foundation (WPF)

Windows Communication Foundation (WCF)

Entity Framework

Windows Workflow Foundation


XSLT support


Runtime design libraries for Entity Framework and WCF Data Services

Managed Extensibility Framework (MEF)

Dynamic types

Parallel-programming features, such as Task Parallel Library (TPL), Parallel LINQ (PLINQ), and Coordination Data Structures (CDS)

Debugging client applications

It does not include (meaning you still need to install the full .NET Framework 4.0 to use those features), for example:


Advanced Windows Communication Foundation (WCF) functionality

.NET Framework Data Provider for Oracle

MSBuild for compiling

Now, it's on Windows update, will it install automatically?

It depends on the Windows Update settings, "the .NET Framework 4 Client Profile is released as a recommended update that may be installed automatically on Windows Vista and Windows 7. The Client Profile is released as an optional update for Windows XP. In Windows XP, you must manually run WU and select the .NET Framework 4 Client Profile".

.NET Framework 4 Client Profile:

  • Recommended Update on Windows Vista/7
  • Optional Update on Windows XP

Full .NET Framework 4:

  • Optional Update on Windows Server 2003, Windows Server 2008 and on Windows Server 2008 R2

More Information?
