OSD - .Net Framework 3.5

The base install of Windows does not come with .Net Framework 3.5 so this package is used during Task Sequences to deploy .Net Framework 3.5 to the applied Operating System. These Frameworks are version specific, while older versions will install fine, it will most likely cause unneeded or unwanted Windows Updates.

Using it in Task Sequences​

In the Task Sequence editor,

  1. Click Add > General > Run PowerShell Script

  2. In the Properties Tab

    • Name: PS1 - Install .Net Framework 3.5
    • Package: OSD - .net Framework 3.5
    • Parameters: -Version [Windows Version] -WinPE

Adding Support for New Windows Releases​

Dependencies​

  • Windows Enterprise ISO
  • Permissions to edit Task Sequences and Packages

Step 1 - Get .Net Framework Package​

  • Make a new folder named the version of windows.
    • Example: 25H2
  • Mount the Windows Enterprise ISO
  • In the mounted ISO, go to sources > sxs
  • Copy the Cab file that contains netfx3 to the created folder
  • Unmount the ISO

Step 2 - Update package​

Package Name: OSD - .Net Framework 3.5
Package Path: \\auth.tamu.edu\TAMU\ConfigMGR\SourceContent\SoftwareDistribution\OAL\OSD\Packages\.Net Framework 3.5

  • Copy the Version folder into the Source folder in the package
  • In MECM, right click and run Update Distribution Points
  • Let is complete before continuing to Step 3

Step 3 - Update Task Sequence​

I would recommend testing your deployment first in Dev Sub Task before deploying it to the Production Sub Task

  • In the Sub Task, select the PS1 - Install .Net Framework 3.5 step
  • Update the current Version value in the Parameters to the new version
