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:

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

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.
