如何删除 Windows 上的 dotnet 运行时? [英] How to remove a dotnet runtime on Windows?

问题描述

我找到了命令 dotnet --list-runtimes 并且它为我输出(缩写):

I've found the command dotnet --list-runtimes and it outputs (abbreviated) for me:

Microsoft.AspNetCore.All 2.1.15 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.All 2.2.0 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.All]
Microsoft.AspNetCore.App 2.1.15 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.2.0 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.2.1 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 2.2.5 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 3.0.0 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 3.1.0 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.AspNetCore.App 3.1.1 [C:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
Microsoft.NETCore.App 2.1.6 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.1.15 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.2.0 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 2.2.5 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 3.0.0 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 3.1.0 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.NETCore.App 3.1.1 [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
Microsoft.WindowsDesktop.App 3.0.0 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]
Microsoft.WindowsDesktop.App 3.1.0 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]
Microsoft.WindowsDesktop.App 3.1.1 [C:\Program Files\dotnet\shared\Microsoft.WindowsDesktop.App]

我想删除特定的 AspNetCore.App 运行时，看看它是否能帮助我解决另一个不同的问题 - 但我不知道怎么做.

I want to remove specific AspNetCore.App runtimes to see if it helps me solve another, different issue - but I don't know how.

我试过了:

• 使用添加/删除程序，但它只列出了.NET Core SDK"条目，而不是运行时(另外:这个列表缺少几个在dotnet --list-runtimes 输出)
• 浏览可用的 dotnet help 条目，但没有看到相关选项
• 浏览remove-runtime-sdk-version readme 但它告诉我使用添加/删除程序，这对我没有帮助

• Using Add/Remove Programs, but it only lists ".NET Core SDK" entries, not runtimes (also: this list is missing several versions that were in the dotnet --list-runtimes output)
• Going through the available dotnet help entries, but saw no relevant option
• Go through the remove-runtime-sdk-version readme but it tells me to use Add/Remove Programs, which doesn't help me

我已经考虑删除我的输出中提到的文件夹，但我对开始删除 Program Files 子文件夹中的文件夹犹豫不决.

I've considered removing the folders mentioned in my output, but am hesitant to just start deleting folders in Program Files subfolders.

是否有 dotnet 命令或其他删除运行时的好方法，特别是 AspNetCore 版本，以便我可以 100% 确定 ASP.NET Core 的版本选择"功能无法选择版本不对?

Is there a dotnet command or other good way to remove runtimes, specifically AspNetCore versions, so that I can be 100% sure that the "Version Selection" feature from ASP.NET Core cannot pick up a wrong version?

根据评论，我尝试了 dotnet-core-uninstall 工具(预览版)，但如果我运行 dotnet-core-uninstall，它会列出零运行时间它可以卸载，只能卸载 SDK(并且只有 2.x 版本).

Per the comments, I've tried the dotnet-core-uninstall tool (preview release), but if I run dotnet-core-uninstall it lists zero runtimes it could uninstall, only SDKs (and only 2.x versions at that).

推荐答案

现在有 官方推荐的卸载 .net 运行时和 sdk 的方法.它的要点是:

There now is a officially recommended method to uninstall .net runtime and sdk. The gist of it is:

• 安装.NET 卸载工具"
• 使用 dotnet-core-uninstall 及其各种命令(list、dry-run 和 remove)

• Install the ".NET Uninstall Tool"
• Use dotnet-core-uninstall with its various commands (list, dry-run, and remove)

小心使用！
