Hi,
By default the .NET Framework 3.5 (includes .NET 2.0 and 3.0) role/feature binaries on 2012R2 do not reside in %SystemDrive%:\Windows\WinSxS
So in order to install you need internet connectivity for Windows Update or point the installer to the Windows 2012R2 media.
How can you configure this so that the binaries are included so installation does not need internet or access to media.
With the uninstall-windowsfeature there is the remove switch which deletes relevant files in %SystemDrive%:\Windows\WinSxS but I cannot see an equivalent that will allow you to add binaries when not installed.
Thanks.
