是否可以在Visual Studio代码空间上使用dotnet 5？我已经按照这里找到的ubuntu 18.04的说明https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu#1804-
运行后：
sudo apt-get install -y dotnet-sdk-5.0
我得到的回复是：
Reading package lists... Done
Building dependency tree
Reading state information... Done
dotnet-sdk-5.0 is already the newest version (5.0.100-1).
0 upgraded, 0 newly installed, 0 to remove and 39 not upgraded.
当我运行dotnet --list-sdks时，我会得到以下版本：
1.1.14 [/home/codespace/.dotnet/sdk]
2.1.807 [/home/codespace/.dotnet/sdk]
2.2.402 [/home/codespace/.dotnet/sdk]
3.0.103 [/home/codespace/.dotnet/sdk]
3.1.301 [/home/codespace/.dotnet/sdk]
为什么5.0没有显示？
当前的解决方案是运行：
curl -sSL 'https://download.visualstudio.microsoft.com/download/pr/820db713-c9a5-466e-b72a-16f2f5ed00e2/628aa2a75f6aa270e77f4a83b3742fb8/dotnet-sdk-5.0.100-linux-x64.tar.gz' | tar -xzC ~/.dotnet
