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

Because of this i am stuck with all my work and really fed up with this

both  CBS and DISM log files are here 

https://www.dropbox.com/s/6orafipl48hikwe/Logs.zip

please help to solve this 

Dism /online /enable-feature /featurename:NetFx3 /All /Source:D:\sources\sxs /LimitAccess

Try adding "/all" like I have in my example and also ensure "J:" is not corrupted media.  Is the /sources/sxs inside that J: drive?  Its saying it can't find the source files which leads me to believe source is bad.  If adding the /all doesn't help and you verified the source is not corrupted then try the command with the /limitaccess removed.  

CBS logs show that x86 files for .NET 3.5 are being found, but not the amd64 ones.

This suggests you're running the 64bit version of Windows 8, but trying to enable .NET 3.5 from the 32bit installation media ...

What do you mean with "manually download"?

CBS logs show that x86 files for .NET 3.5 are being found, but not the amd64 ones.

This suggests you're running the 64bit version of Windows 8, but trying to enable .NET 3.5 from the 32bit installation media ...

So how would one go around this? I haven't been able to enable it through control panel since the download keeps dropping, and there really aren't x64 folders in the sources\sxs folder in the Windows 8 DVD from which I installed the x64 version of Windows, only x86... Any ideas? Any help would be greatly appreciated, I can't do anything without it!

You rock dude your line of code did do the required thing.
