更新 Visual Studio 2019 删除了 .NET Core 3.1 SDK

Question

My operating system is Windows 10 Pro .

I had Visual Studio 2019 Community 16.4.5 Version installed. When I open PowerShell and run dotnet --list-sdks command, it list these 3 .NET Core SDKs:

1.0.0-preview2-003131 [C:\Program Files\dotnet\sdk]
2.1.526 [C:\Program Files\dotnet\sdk]
3.1.101 [C:\Program Files\dotnet\sdk]

So the latest .NET Core SDK was 3.1.101 .

Now in Visual Studio 2019 Community I had to work with .NET 5.0 projects which was not possible with current configuration. So I took these steps:

1. I install .NET 5.0 SDK .
2. I update Visual Studio 2019 Community to Visual Studio 2019 Community 16.11.15 Version via Visual Studio Installer .

Now in Visual Studio 2019 Community I can work with .NET 5.0 projects. Great.

But I have lost .NET Core 3.1 SDK. When I open PowerShell and run dotnet --list-sdks command, it list these 3 .NET Core SDKs:

1.0.0-preview2-003131 [C:\Program Files\dotnet\sdk]
2.1.526 [C:\Program Files\dotnet\sdk]
5.0.408 [C:\Program Files\dotnet\sdk]

I was expecting that 4 .NET Core SDKs will be listed, as you can see 3.1.101 is missing.

Why 3.1.101 was deleted? I confirmed via File Explorer that C:\Program Files\dotnet\sdk folder does not have 3.1.101 folder anymore.

I can just say, when I want to install other .net core version in my Visual studio, I usually open the visual studio installer , then click Modify , then go to Individual components` and install them.
