Could someone advise if when I'm using Horizon 2111 with Windows 10 2009 LTSC I should still be installing .Net 3.5 on the Gold Image please?

According to the "Manually Creating Optimized Windows Images for VMware Horizon VMs" I should be installing .Net 3.5 but I wanted to check!

I'm working with a customer who has an existing Windows 10 2009 LTSC base image that is used for physical desktops that has .Net 4.7 installed . I did not install .Net 3.5 and the pool of desktops appears to be working flawlessly.

Do I need to enable .Net 3.5 and if so why?

Thanks,

Greg
