How to install dotNet Framework 3.51 on Windows Server 2012 core

dotnet-frameworkwindows-server-2012windows-server-core

On Windows Server 2008 R2 core I use dism.exe and the featurename: 'NetFx3-ServerCore' this feature is not available on Server 2012 (Windows Server 8).

Using the standard 3.51 Installer on Server 2012 Core tells me: "You must use the Role Management Tool to install or configure Microsoft .NET Framework 3.5"

In the GUI version (of Server 2012) I can do this and it downloads a package from Microsoft.com, but how do I do this on Core?

You can use Powershell to show the available Windows Features:

Import-Module ServerManager
Get-WindowsFeature | out-file C:\WindowsFeatures.txt -width 300

Because the data is a long and wide it is better to pipe it into a file and review it there.

it shows that '.NET Framework 3.5 Features' are available, but '.NET Framework 3.5 (includes .NET 2.0 and 3.0)' has been removed.

However, the files are still on the DVD, you can use:

dism /online /enable-feature /featurename:NetFX3 /source:D:\sources\sxs /all /LimitAccess

or the PowerShell 'Add-WindowsFeature' commandlet to install it:

Add-WindowsFeature –name NET-Framework-Core -source D:\sources\sxs

Edit: On Server 2012 R2 with Update 1 installed (KB2919355) this doesn't work if you are using the original DVD/ISO. You need a DVD or ISO which includes that update. For new installations, install .NET 3.5 before you apply KB2919355.

Normally you just need to make sure that you have .NET installed and then Windows Update will lead you through all of the update. However I've run into failures like yours on about 1 in 50 servers, so the trick is to figure out the best path to navigate for your situation.

You're on the right path. Here's what I suggest:

For the WS08 server, I would uninstall the .NET Framework completely and then build back up again. To do so, use Add/Remote programs to uninstall any of the service packs that you see there. Then from Server Manager go to -> Roles -> Web Server (IIS) -> Remove Role Services -> and remove "ASP.NET" and ".NET Extensibility" (and accept the prompt to remove dependencies). After that completes, perform a reboot if it asks for one.

Then, from Server Manager again, add a role service and add those back again. Then use Windows Update, but step through the service packs in order. Don't assume that the cumulative installs will work since you already know that you're a fringe case.

For the Vista computer, if you haven't already, I suggest the Windows Update path there too. If that dead-ends, then start here: http://www.microsoft.com/net/Download.aspx. Make sure that you do have .NET 2.0 installed. (just check c:\windows\microsoft.net\framework\v2.0.50727 and make sure it has the full set of files.).

Then install 3.5 (not SP1 yet): http://www.microsoft.com/downloads/details.aspx?FamilyId=333325FD-AE52-4E35-B531-508D977D32A6&displaylang=en

Finally 3.5 SP1: http://www.microsoft.com/downloads/details.aspx?FamilyId=AB99342F-5D1A-413D-8319-81DA479AB0D7&displaylang=en

Hope that helps.
