Dot Net FrameWork 4.8 feature not showing for IIS on Windows Server 2019

Question

I tried to install dot net 4.8 framework runtime on Windows Server 2019 that is an AWS EC2 instance and kept getting error
" Exe (C:\ae3d5ec71a149db27aa40d203b1830\x64-Windows10.0-KB4486153-x64.cab) failed with 0x80092004 - Cannot find object or property"

After fighting with it I finally got KB4486153 installed using DISM tool, and it showed up on installed updates.
Nevertheless when I try to turn on dot net 4.8 feature for IIS only the default 4.7 is shown.

Any suggestions ?

Thanks!

Hi @Lee ,

If you have installed .NET framework 4.8, server manager won't update in time to show 4.8. So check out the current .net version in this way is not accurate.

You can check it use RuntimeInformation.FrameworkDescription property to query for which .NET implementation and version your app is running on.
Another way is checking registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full. If the Full subkey is missing, then .NET Framework 4.5 or above isn't installed. The Release REG_DWORD value in the registry represents the version of .NET Framework installed.

.NET Framework 4.8 On all other Windows operating systems (including other Windows 10 operating systems): 528049

Your release REG_DWORD value is 528049, so .NET 4.8 has installed on server.

How to: Determine which .NET Framework versions are installed

Inbox feature names do not change with updates
.NET 4.8 already updated .NET 4.7 under the hood
