Windows Vista, .NET Framework 3.0 Runtime and Windows SDK Downloads
Microsoft released .NET Framework 3.0. I think many developers not finished migration to .NET 2.0 yet and we already have new bits :). I love it – new stuff to explore.
.NET Framework 3.0
With the exception of Windows Vista (which by default includes the .NET Framework 3.0), all operating systems require you to install the .NET Framework 3.0 in order to run and develop managed applications. Some sample tools included in the Windows SDK also require you to install the .NET Framework 3.0.
Windows Longhorn Server
The .NET Framework 3.0 Runtime components ship with Longhorn Server, but are only installed if you choose the AppServer role. Windows Longhorn Server does not include the .NET Framework 3.0 by default.
Visual Studio 2005 Extensions
Download Visual Studio 2005 Extensions for WCF, WP to install the Workflow Foundation, Windows Communication Foundation, and Windows Workflow Presentation project templates into Visual Studio. Using these extensions requires Visual Studio 2005 Professional Edition. These packages were previously known as the “Orcas Tools for .NET 3.0 (formerly WinFX) CTP.” Note: Extensions for WCF, WPF are not supported and are distributed as a community technology preview.
Windows SDK
The Windows SDK contains documents, samples, APIs, and tools for both managed and native programming. Download the SDK for Windows Vista C++ headers and APIs.
