How to download and install .Net Framework 3.5(include .net 2.0 and 3.0) in Windows 8

When i going to download  .Net Framework 3.5 (include .net 2.0 and 3.0) using the windows features, I got the error 0x800F0906 in many times...

then i try to  install using with DISM using the below command,

dism.exe /online /enable-feature /featurename:NetFX3/Source:J:\sources\sxs /LimitAccess

where the my ISO image mount driver is J and I've got the below error 

C:\Windows\system32>dism.exe /online /enable-feature /featurename:NetFX3 /Source
:J:\sources\sxs /LimitAccess

Deployment Image Servicing and Management tool
Version: 6.2.9200.16384

Image Version: 6.2.9200.16384

Enabling feature(s)
[===========================65.8%======                    ]

Error: 0x800f081f

The source files could not be found.
Use the "Source" option to specify the location of the files that are required t
o restore the feature. For more information on specifying a source location, see

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log
