HI All,

Cannot install .net framework 3.5 on Windows 10 on ARM Insider Preview image, is it not supported?

I used the Windows 10 ARM insider Preview "VHDX" to setup this Windows.

From link:

https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewARM64

I tried DISM/UI also installation failure with 0x800F0950, I tried to find this ARM version ISO to install from source.

However, there is no ISO provided (just has the VHDX)

Would like to confirm is Windows 10 on ARM Insider Preview image not supported .net framework 3.5 to be installed? Thanks.

    I have the exact same problem when turning on the .NET Framework 3.5 on ARM, "Windows couldn't complete the requested changes, Error code: 0x800F0950".  Really hoping for a fix

    Yeah, and not even Microsoft's own err.exe can resolve what this error code means.

    Same issue ... running Windows 10 ARM 64 on a Silicon Mini. Will not install NetFrame 3.5 or any other version with or with Features set.

    Quick notice, please verify whether your .NET applications work or do not work, after installing KB5001030 from Windows Update. This KB is not listed on the Knowledge Base articles site, but is the latest .NET 3.5 and 4.8 Cumulative Update for Windows for ARM. I did not need to manually install the .NET 3.5 feature pack to get this update within a day of my last main cumulative OS update. I did not test this myself yet, but others have found that their .NET stuff just works, and does not require the feature pack to be installed separately.
