Uninstalling older dotnet versions

Question

Hi, I am running a vulnerability scan on one of our servers which is running Microsoft .NET version 8.0.8. The scan is reporting a vulnerability with this version so I installed version 8.0.11. However, when I run dotnet --info command, the output shows that I have 8.0.8 and 8.0.11 installed. I tried using the dotnet-core-uninstall' tool but that does not list 8.0.8 installed. Therefore, this still shows up as a vulnerability. How do I remove the 8.0.8 version?

C:\Program Files (x86)\dotnet-core-uninstall>dotnet --info

Hi @Shiraz Jauffer ,

First try uninstalling the unwanted NET runtime in the Uninstall or Change program in the Control Panel。

If it not listed, you can manually remove them.

• Open File Explorer and go to:
  • C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App
  • C:\Program Files\dotnet\shared\Microsoft.NETCore.App
  • C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App
• In each of these directories, locate the folder named 8.0.8 and delete it.
• Run dotnet --info again to ensure the 8.0.8 runtime is no longer listed.

Best Regards.

It looks like you have the SDKs installed on the server. The Window's add/remove programs works well for removing SDKs and runtimes.

Otherwise, the dotnet-core-uninstall list command lists the SDKs that can be removed using the Uninstall Tool.
