DOT NET 3.5 for Windows 10 Technical Preview


DOT NET 3.5 was often hard to install on Windows 8, 8.1, 2012, and 2012 R2. I tested installing it on Windows 10 Technical Preview for Enterprise:

Win10e40

In Control Panel\Programs\Programs and Features, click turn Windows features on or off, and check the “.NET Framework 3.5” box and click OK

Win10e41

Click “Download files from Windows Update”

Win10e42

 

Win10e43

 

Win10e44

It just works!

Same can be done via the DISM command line utility:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All

Win10e47

Again it works just fine!

  3. Follow this video: https://www.youtube.com/watch?v=fdfvJCAN0Mw

    Preparation:
    Windows 10 DVD, ISO image or your bootable flash drive with Windows 10

    Directions:

    1. Insert your Windows 10 DVD, or double click its ISO image, or insert your bootable flash drive with Windows 10, depending on what you have.

    2. Open ‘This PC’ in File Explorer and note the drive letter of the installation media you have inserted. In my case it is disk I:
    3. Open CMD with administrative privileges and type the following command:
    Dism /online /enable-feature /featurename:NetFx3 /All /Source:X:\sources\sxs /LimitAccess

    Replace X with your drive letter for Windows 10 installation media.

    It takes 20 minutes to complete. Thanks for watching.
