It asked me to enable .Netframework 3.5 or disable it.
I choose disabled it.

I faced this issue on my tiny11 too. I don't remember the console command but what u have to do is reinstall dotnet 3.5 using your official 11 image. You can use chat gpt for the command, it worked for me too

my mistake was tiny11core asked my about dotnet 3.5 enable or disable, it also said, you will not be able to enable it later, if you choose disabled, but i ignored.

i tried to enable it by Untouch Windows 11 iso, which i had used before for creation of modified iso.
but it not worked, tried several commands in cmd and powershell. but not succeeded.

everything is working fine, but some app which need dotnet, not work.

I tried every thing to enable dotnet, but failed.
it was said by program, you will be not able to enable it again later, but i had ignored it.

luckily i had original iso, which i had download from microsoft website before.

i again created tiny iso by tiny11Coremaker.ps1 , but this time i enabled dotnet 3.5.
it was only smooth way, instead i wasted time.
now everything is fine, even before everything was good, only issue was 1 app needed to install dotnet to run that app.

thanks developer.

i want to suggest other users.

download "US version" , "Windows 11 iot Enterprise Ltsc", from microsoft official website
(US version is less bloatware, also stay away "N" version of enterprise, they are buggy)

it has "iot enterprise ltsc" and "enterprise ltsc"
choose "enterprise ltsc", while using tiny11 script, otherwise window will ask for drivers of iot devices during installation.

i had downloaded this from Microsoft site.

en-us_windows_11_iot_enterprise_ltsc_2024_x64_dvd_f6b14814
(size 4.79GB)

use ""tiny11Coremaker.ps1" , but choose option "enable dotnet 3.5".

it will decrease size to "2.68 GB" if you enable dotnet 3.5, otherwise it will decrease size to "2.63GB",
by disabling dotne3.5 , few app will not work, whose requirement is dotnet. others app will work.
