It has been barely 3 months since we shipped the previous Windows SDK prerelease; and here we are today shipping another prerelease version of the Windows SDK.  This SDK coincides with the release of Microsoft® Visual Studio® 2008 Beta2 and Microsoft® .NET Framework 3.5 Beta2.  If you want to be on the cutting edge of .NET Framework 3.5 development, this SDK is for you.  Our SDK even has a catchy new name, the Windows SDK for Windows Server® 2008 and .NET Framework 3.5.


Here’s a quick rundown of what’s new in this SDK:

·         The latest set of documentation and samples for .NET Framework 3.5 development. 

·         New and updated tools for .NET Framework 3.5 development

·         A new C++ compiler and associated CRT

·         This SDK will install side-by-side with Microsoft® Visual Studio® 2008 Beta2.


As was the case with our previous prerelease SDK, this SDK is compatible with the RTM release of Microsoft® Visual Studio® 2005 SP1 and the Microsoft® Visual Studio® Express Editions, which are available to download, free of charge.


As always, we strongly recommend reading the Release Notes for a description of known issues with this SDK.  A few items worth calling out are the following:

·         To take advantage of .NET Framework 3.5 features, such as new samples or tools, you’ll need to install the Microsoft® .NET Framework 3.5 Beta2

·         If you want to use Microsoft® Visual Studio® 2005 with existing SDK C++ samples you can.  If you want to take advantage of and try out the latest C++ command line compiler that ships in this SDK on those same samples, you’ll need to upgrade those sample projects as described in the Release Notes.

·         This release of the SDK is an ISO-only download.  This means that you will need to download the entire ISO and then either burn it to a DVD to use in your local DVD drive, mount it virtually as if it were another drive, or copy the contents locally, in order to run the SDK’s setup.exe.  More details about how to work with the DVD ISO image can be found at the download page for the SDK


We encourage you to install this SDK on a test machine and let us know what you think.
