Windows Server 2019 Cannot Install .NET 3.5
I am running Windows Server 2019 (Version 1809, Build 17763.4499) and I cannot install .NET Framework 3.5. Below is the current installation status of the feature on my machine: PS > Get-WindowsFeature -Name NET-Framework-Features,NET-Framework-Core,NET-HTTP-Activation,NET-Non-HTTP-Activ Display Name Name Install State ------------ ---- ------------- [X] .NET Framework 3.5 Features NET-Framework-Features Installed [ ] .NET Framework 3.5 (includes .NET 2.0 and 3.0) NET-Framework-Core Removed [ ] HTTP Activation NET-HTTP-Activation Removed [ ] Non-HTTP Activation NET-Non-HTTP-Activ Removed Through hours of searching online I have not been able to discover a resolution to the issue I am seeing. I followed the installation steps in https://woshub.com/how-to-install-net-framework-3-5-on-windows/ as this was the most complete guide. None of the suggested installation methods worked. Via Server Manager: Add roles and features -> Features -> .NET Framework 3.5 Features -> .NET Framework 3.5 (includes .NET 2.0 and 3.0 ); Using DISM: DISM /Online /Enable-Feature /FeatureName:NetFx3 /All Using DISM: DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /Source:D:\sources\sxs /LimitAccess With PowerShell: Install-WindowsFeature -Name NET-Framework-Core With PowerShell: Install-WindowsFeature -Name NET-Framework-Core -Source D:\Sources\SxS With DISM: DISM /online /Add-Package /PackagePath:D:\Sources\SxS\microsoft-windows-netfx3-ondemand-package~31bf3856ad364e35~amd64~~.cab I also tried using the offline packages from my installation media without success. And when trying to use GPO to force installation from / prohibit installation from Windows Update (non-WSUS) I did not see any results. Regardless which method I use, I end up getting the same 0x800f0800 error. I've only come across https://social.technet.microsoft.com/Forums/windowsserver/en-US/5be0b03c-f499-4530-837d-76eacb4f1473/net-framework-35-cannot-install when trying to install a Windows feature, but their resolution was just rebuilding their server. This is not a viable option for my scenario. The full error from PowerShell is displayed below: PS> Install-WindowsFeature -Name NET-Framework-Core -Source D:\Sources\SxS Install-WindowsFeature : The request to add or remove features on the specified server failed. Installation of one or more roles, role services, or features failed.

.Net 4.8 not showing in "Windows Features" for Windows Server 2019
Hello, We have installed .Net 4.8 on a Windows Server 2019 OS, and it wont show under "Windows Feautures". What we see there is only .Net 3.5 and .Net 4.7. It´s crucial that we see .Net 4.8 in "Windows features" so we can turn on/off some features needed for us in order to run our programs that we use. Reading this thread with the same issue: https://techcommunity.microsoft.com/t5/windows-server-for-it-pro/server-2019-net-4-8-not-showing-in-features/m-p/3714980 One comment told OP that its included in Windows, but it wasnt included in our windows. And even if it was, we still need to see the .Net 4.8 so we can turn on and off some features. What can we do?
