删除过时的目标框架（警告 NETSDK1138）

Question

我在运行时收到此警告dotnet new -i "<some-template>"：

/usr/local/share/dotnet/sdk/5.0.100/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.EolTargetFrameworks.targets(28,5): warning NETSDK1138: The target framework 'netcoreapp1.0' is out of support and will not receive security updates in the future. Please refer to https://aka.ms/dotnet-core-support for more information about the support policy.

链接https://aka.ms/dotnet-core-support不包含任何关于netcoreapp1.0.

dotnet --list-sdks 显示这个结果：

2.1.300 [/usr/local/share/dotnet/sdk]
3.1.101 [/usr/local/share/dotnet/sdk]
3.1.201 [/usr/local/share/dotnet/sdk]
3.1.302 [/usr/local/share/dotnet/sdk]
5.0.100 [/usr/local/share/dotnet/sdk]

这是否意味着我必须删除2.1.300？

据该网站称，支持2.1.300将于 2021 年 8 月 21 日结束。

这是输出dotnet --list-runtimes：
