.NET uninstall tool

  • Article
  • 11 minutes to read

The .NET uninstall tool (dotnet-core-uninstall) lets you remove .NET SDKs and runtimes from a system. A collection of options is available to specify which versions you want to uninstall.

The tool supports Windows and macOS. Linux is currently not supported.

On Windows, the tool can only uninstall SDKs and runtimes that were installed using one of the following installers:

  • The .NET SDK and runtime installer.
  • The Visual Studio installer in versions earlier than Visual Studio 2019 version 16.3.

On macOS, the tool can only uninstall SDKs and runtimes located in the /usr/local/share/dotnet folder.

Because of these limitations, the tool might not be able to uninstall all of the .NET SDKs and runtimes on your machine. You can use the dotnet --info command to find all of the .NET SDKs and runtimes installed, including those SDKs and runtimes that the tool can't remove. The dotnet-core-uninstall list command displays which SDKs can be uninstalled with the tool. Versions 1.2 and later can uninstall SDKs and runtimes with version 5.0 or earlier, and previous versions of the tool can uninstall 3.1 and earlier.

Install the tool

You can download .NET uninstall tool from the tool's releases page and find the source code at the dotnet/cli-lab GitHub repository.

Note

The tool requires elevation to uninstall .NET SDKs and runtimes. Therefore, it should be installed in a write-protected directory such as C:\Program Files on Windows or /usr/local/bin on macOS. For more information, see the Elevated access for dotnet commands and the detailed installation instructions.

Run the tool

The following steps show the recommended approach for running the uninstall tool:

Step 1 - Display installed .NET SDKs and runtimes

The dotnet-core-uninstall list command lists the installed .NET SDKs and runtimes that can be removed with this tool. Some SDKs and runtimes might be required by Visual Studio and they're displayed with a note of why it isn't recommended to uninstall them.

Note

The output of the dotnet-core-uninstall list command won't match the list of installed versions in the output of dotnet --info in most cases. Specifically, this tool won't display versions installed by zip files or managed by Visual Studio (any version installed with Visual Studio 2019 version 16.3 or later). One way to check if a version is managed by Visual Studio is to view it in Add or Remove Programs, where Visual Studio managed versions are marked as such in their display names.

For more information, see list command later in this article.

Step 2 - Do a dry run

The dotnet-core-uninstall dry-run and dotnet-core-uninstall whatif commands display the .NET SDKs and runtimes that will be removed based on the options provided without performing the uninstall. These commands are synonyms.

For more information, see dry-run and whatif commands later in this article.

Step 3 - Uninstall .NET SDKs and Runtimes

dotnet-core-uninstall remove uninstalls .NET SDKs and Runtimes that are specified by a collection of options. Versions 1.2 and later can uninstall SDKs and runtimes with version 5.0 or earlier, and previous versions of the tool can uninstall 3.1 and earlier.

Since this tool has a destructive behavior, it's highly recommended that you do a dry run before running the remove command. The dry run will show you what .NET SDKs and runtimes will be removed when you use the remove command. Refer to Should I remove a version? to learn which SDKs and runtimes are safe to remove.

Caution

Keep in mind the following caveats:

  • This tool can uninstall versions of the .NET SDK that are required by global.json files on your machine. You can reinstall .NET SDKs from the Download .NET page.
  • This tool can uninstall versions of the .NET Runtime that are required by framework dependent applications on your machine. You can reinstall .NET Runtimes from the Download .NET page.
  • This tool can uninstall versions of the .NET SDK and runtime that Visual Studio relies on. If you break your Visual Studio installation, run "Repair" in the Visual Studio installer to get back to a working state.

By default, all commands keep the .NET SDKs and runtimes that may be required by Visual Studio or other SDKs. These SDKs and runtimes can be uninstalled by listing them explicitly as arguments or by using the --force option.

The tool requires elevation to uninstall .NET SDKs and runtimes. Run the tool in an Administrator command prompt on Windows and with sudo on macOS. The dry-run and whatif commands don't require elevation.

For more information, see remove command later in this article.

Step 4 - Delete the NuGet fallback folder (optional)

In some cases, you no longer need the NuGetFallbackFolder and may wish to delete it. For more information, see Remove the NuGetFallbackFolder.

Tip

Response files are an alternative to placing all the versions on the command line. They're text files, typically with a *.rsp extension, and each version is listed on a separate line. To specify a response file for the VERSION argument, use the @ character immediately followed by the response file name.

Options

  • --all

    Removes all the .NET SDKs and runtimes.

    Removes all the .NET SDKs and runtimes, except those versions specified.

  • --all-but-latest

    Removes the .NET SDKs and runtimes, except the highest version.

    Must be used with --sdk, --runtime, and --aspnet-runtime to remove x64 SDKs or runtimes.

  • --x86

    Must be used with --sdk, --runtime, and --aspnet-runtime to remove x86 SDKs or runtimes.

  • --force

    Forces removal of versions that might be used by Visual Studio.

Note

  • Exactly one of --sdk, --runtime, --aspnet-runtime, and --hosting-bundle is required.
  • --all, --all-below, --all-but, --all-but-latest, --all-lower-patches, --all-previews, --all-previews-but-latest, --major-minor, and [<VERSION>...] are exclusive.
  • If --x64 or --x86 aren't specified, then both x64 and x86 will be removed.

Examples

Note

By default, .NET SDKs and runtimes that might be required by Visual Studio or other SDKs aren't included in the dotnet-core-uninstall dry-run output. In the following examples, depending on the state of the machine, some of the specified SDKs and runtimes might not be included in the output. To include all the SDKs and runtimes, list them explicitly as arguments or use the --force option.
