Released: Windows SDK for Windows 7 and .NET Framework 3.5 SP1: RC

The Windows SDK for Windows 7 and .NET Framework 3.5 SP1: Release Candidate has been released in both ISO and Web Setup format.  Web setup allows you to install a specific subset of the SDK you select without having to download the entire SDK; whereas the DVD ISO setup allows you to download the entire SDK to install later.  Please note, with this release of the SDK, there are 3 ISOs to choose from based on the CPU (x86, x64, or Itanium) platform you are installing on. Each ISO will however allow you to build applications that target all the other CPU platforms.  Thus if you install the x86 ISO (which only installs on x86 platforms), you will be able to create applications targeting x86, x64, and Itanium.


Platform Compatibility:

This release of the Windows SDK is compatible with Windows 7 Release Candidate,  Windows Server 2008 R2 Candidate,  Windows Server 2008, .NET Framework 3.5 Service Pack 1 , Windows Vista, and Windows XP.


Visual Studio Compatibility:

This release of the Windows SDK is compatible with Visual Studio 2008; including Visual Studio Express Editions.

The following is a small sampling of what’s new or updated in this SDK.

·         Documentation – Approximately 80% of the SDK documentation set has been refreshed

  1. Thank you for submitting this cool story – Trackback from DotNetShoutout

  2. Ormai sappiamo tutti che questo è un periodo intenso per quanto riguarda i rilasci: dopo Windows 7 RCe

    Does this update include the updated Direct2D/DirectWrite or do we still need to use the DirectX Mar 09 SDK for that?

  4. My latest in a series of the weekly, or more often, summary of interesting links I come across related to Visual Studio. New on Visual Studio Gallery: VSGesture VS2008 KB: Hotfix available for When you debug in Visual Studio 2008 Service Pack 1, more

  5. With all the talk about Windows 7 on the client, we haven’t talked much about the server platform that

    The biggest enhancement you could do for future versions is separate the IA64 bits so developers don’t have to download huge bits for that lesser used platform.

  7. The toolkit needed for you to test your systems and devices for Windows 7 and Windows Server 2008 R2

  8. says:

    The .NET team has got it right with .NET 4. Separate redistributables for x86, x86_64 and x86_IA64. Please do the same for Windows SDK and WAIK.

    Thank you for your comment, someone (May 12, 2009).  There is indeed a way to not download the IA64 libraries

    Start Web Setup from (486KB)

    Select Run (or Save it and then run it from the location saved to)

    Once setup launches, choose where you would like the SDK installed.

    Under Installation options, select what you would like to install.

    On the installation options screen, deselect the IA64 libraries.  This will save 22.1 megs.

    Currently, there is not a way to not download the IA64 cross compiler binaries with the rest of the compiler binaries unless you choose to not install "Visual C++ Compilers".  We evaluate separating this out for future Windows SDK versions.

    Looking forward to seeing how smoothly .net frame work 3.5 runs on Windows 7.

  13. ipang says:

    I have been using the beta version of Windows 7 and it works really well compare to Vista to be honest. Vista is slow specially when we copy and paste large file(s).

    Looking forward to see this .net framework 3.5 doing better than previous version.

    Windows SDK installation fails with following error:


    A problem occurred while installing selected Windows SDK components.

    Installation of the "Microsoft Windows SDK for Windows 7" product has reported the following error: Please refer to SamplesSetupHTMLConfigDetails.htm document for further information.


    Any idea what’s wrong?

  15. Rezultate Live says:

    I have the same problem as @Pariuri Sportive, i can’t see anything in the ConfigDetails.htm that could help me.. anyone?

  16. MSDN Archive says:

    Rezultate Live and Pariuri Sportive, This error usually occurs when you have a corrupted Document Explorer installation. To fix this, I recommend that you uninstall the Document Explorer through Programs and Settings (or Add Remove Programs on pre-Vista OSes). Next, re-try the Windows SDK Installation.

    If uninstalling Document Explorer fails with errors similar to “Unable to open key” you may wish to refer to the solution explained here to uninstall Document Explorer:
