ConfigMgr Install .NET Framework during OSD Task Sequence

There is already a lot of information on this topic. Building a reference image including .NET Framework features installed. The thing is, there is no real one way to go. So combining some solutions together I came up with the following.

For installing the .NET Framework features, Windows needs additional sources located on the Windows installation media (ISO). Look for a folder called sxs. (drive:\sources\sxs)

Copy this sxs folder and create a ConfigMgr Package, with no program and distribute the content.

In the Task Sequence go to Add - General - Run Command Line

The most important is to add the Package and specify the source option in the command.

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:"."

Bacause the working folder will default to the package location a dot (".") is sufficient to specify.

This will save me a lot of time in future deployments.

Happy deploying...

Installing .NET Framework 3.5 during Task Sequence

Have you ever tried enabling .NET Framework during OS deployment in a Task Sequence? Instaling Windows 8.1 this should be enabled easily by running the following command line:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All

However, it's not as easy as it looks. This task often fails with error 0x800f081f during TS deployment. Also if you try to install .NET Framework offline by mounting the image it fails with the same error, see below.

Searching around I found out that 2 packages are prohibiting the .NET Framework action from succeeding. Package KB2966826 and KB2966826 are both integrated in the default Windows 8.1 installation.

Solution:
To enable .NET Framework in the first place both packages should be removed. These actions can be run as Command Line action in the Task Sequence.

Uninstall KB2966826

• DISM /Online /Remove-Package /PackageName:Package_for_KB2966826~31bf3856ad364e35~amd64~~6.3.1.7 /quiet /norestart

Uninstall KB2966828

• DISM /Online /Remove-Package /PackageName:Package_for_KB2966828~31bf3856ad364e35~amd64~~6.3.1.4 /quiet /norestart

After removing the packages, the .NET Framework feature can be installed succesfully using the comand line below.

• DISM /Online /Enable-Feature /FeatureName:NetFx3 /All

The KB updates can be installed afterwards using the Software Updates step. These actions can be run in the Build and Capture phase, so .NET is available in every deployment.
