I think, this bug is probably the same as descibed in https://forum.winreducer.net/t2383-ex-100-v1-9-12-0-rs3-build-16299-15-integrate-updates-breaks-net-framework-3-5.
But because there are several bugs handled in this thread, I'd rather open a new one.
First my wccf: klick
Although update cleanup is not enabled, .Net3.5 cannot be enabled, neither through the Windows Features dialog, nor with DISM. In both cases I get the same error message:
"The referenced assembly could not be found."
If I already integrate .Net3.5 into the ISO, it works fine with the same wccf.
