Answer 1

There is an uninstall tool released by .Net team. The tool lets you clean up .Net SDKs and Runtimes on a system. You can download the tool from the following URL.

https://github.com/dotnet/cli-lab/releases

To find more details about the too, refer the following URL

https://learn.microsoft.com/en-gb/dotnet/core/additional-tools/uninstall-tool?tabs=windows

Once you installed the tool, you can use the commands, few useful commands are below.

To list the .Net SDKs & runtimes that can be uninstalled >> dotnet-core-uninstall list

There is a dry-run option that will displays the SDKs / Runtimes that will be removed based on the options you provided to the command.

e.g. >> dotnet-core-uninstall dry-run

For example, the follwoing command will dry run of removing all SDKs below the version 2.2.301

dotnet-core-uninstall whatif --all-below 2.2.301 --sdk

and the following command will remove all SDKs below the version 2.2.301

dotnet-core-uninstall remove --all-below 2.2.301 --sdk

Hi @Roger Roger ,

According to your description, I suggest you could try to use dotnet uninstall tool to uninstall the SDK.

You could download it from this github link.

Then you could use below codes to uninstall the SDK:

dotnet-core-uninstall remove 2.1.12 --sdk --yes  

More details, you could refer to this article.
