    windows 8 (Developer Preview)

    For some reason, there is no problem for me installing (enabling) NET.Framework 3.5 under win 8 feature with accessing stuff.
    Just for information, I'm using the 512KB dial up connection and only took 5 minutes untill it flawlessly finished. While downloading the standalone version took me 4 hours, yet still when I tried to install it windows still had to ran the access to internet, and never finished completely.

    So, Paarkhi.... Never affraid that enabling that feature internally will take time as you download the standalone version (if that is your consern, then this my answer)

    Still, I'm still figuring out how to install the standalone version without accessing the internet. (just for some reason).
    Thank you forum.

    Indeed, place your DVD or USB drive in the computer and run "dism.exe /online /enable-feature /featurename:NetFX3 /Source:X:\sources\sxs" where "X" is the DVD drive or USB letter (in an elevated command prompt), seems to be a viable fix for those having issues.

    Windows 8 Developer Preview x64 with Dev Tools

    Dism worked perfectly.. .net 3.5.1 is in the installation DVD itself

    If the user performs a clean installation of Windows Developer Preview, apps that require .NET Framework 3.5 (or 2.0) will trigger a request for the necessary files. Normally the missing files will be downloaded from Windows Update (after asking the user for permission), but if access to Windows Update is not possible, enabling .NET Framework 3.5 will fail.

    To enable .NET Framework 3.5 on only a few machines with clean installs of Windows Developer Preview:
    1.Copy\sources\sxs\ from the mounted operating system build ISO image to dotnet35 or similar folder. For example:
    xcopy e:\sources\sxs\*.* c:\dotnet35 /s
    2.Execute the following command line using admin privileges:
    Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\dotnet35 /LimitAccess

    Original post by Andre.Ziegler @ Anyone traced the .NET 3.5.1 download (x64)?

    Worked perfectly for me.

    I found an offline method here: Enable .NET Framework 3.5.1 on Windows 8 Developer Preview to Run Applications

    I need to get this in also. I have .net 3.5 but not 3.5.1 does that matter?

    None of these fixes work for me sadly ... might have to be a re-install!

    You could read carefully the Windows 8 Consumer Preview and Windows Server 8 Beta Compatibility Cookbook. I found some explanations and steps to do so on section titled ".NET Framework 4.5 Is Default and .NET Framework 3.5 Is Optional".
