How to enable/Install Microsoft . Net Framework
we can enable the .NET Framework 3.5 by using the Deployment Image Servicing and Management (DISM) command-line tool and specifying the installation media (ISO image or DVD) you installed Windows 8 from.
1.In Windows 8 or Windows Server 2012, open a Command Prompt window with administrative credentials (that is, choose Run as administrator).
2.To install the .NET Framework 3.5 from installation media located in the D:\sources\sxs directory, use the following command:
DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs
where:
¦/Online targets the operating system you're running (instead of an offline Windows image).
¦/Enable-Feature /FeatureName:NetFx3 specifies that you want to enable the .NET Framework 3.5.
¦/All enables all parent features of the .NET Framework 3.5.
¦/LimitAccess prevents DISM from contacting Windows Update.
¦/Source specifies the location of the files needed to restore the feature (in this example, the D:\sources\sxs directory).
