Install .NET Framework 3.5 on Windows 10

25-04-2017

On Windows 10 is not possible to install .NET Framework 3.5 using the Turn Windows features on or off option because the error 0x800F081F. In my case I installed it following the steps below:

1. Go to https://my.visualstudio.com and download Windows 10 Features on Demand iso (x86 or x64).

2. Mount the iso

3. Open a PowerShell command line as Administrator and run the next command

Dism /online /enable-feature /featurename:NetFX3 /All /Source:D:\ /LimitAccess

The output should something like this:

Deployment Image Servicing and Management tool
Version: 10.0.14393.0

Image Version: 10.0.14393.0

Enabling feature(s)
[==========================100.0%==========================]
The operation completed successfully.

If you go to Turn Windows features on or off the option fot .NET Framework 3.5 must be cheked.
