当然sdk使用2.2.108比2.2.110可能要稳一点,微软官方开发环境的最佳sdk版本图:
OS | Development Environment | .NET Core SDK |
Any supported | Command line and/or Visual Studio Code | 2.2.401 |
Windows | Visual Studio 2019 version 16.2 | 2.2.401 |
Windows | Visual Studio 2019 version 16.1 | 2.2.301 |
Windows | Visual Studio 2019 version 16.0 | 2.2.205 |
Windows | Visual Studio 2017 | 2.2.108 |
二,验证过程
1.卸载(参照:微软文档):
dpkg --list #查看安装的包
#apt-get remove 要删除的包
apt-get remove dotnet-host
apt-get remove dotnet-hostfxr
apt-get remove dotnet-runtime
apt-get remove dotnet-sdk-2.2
2.安装:
wget -q https://packages.microsoft.com/config/ubuntu/18.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install dotnet-sdk-2.2=2.2.110-1
#sudo apt-get install dotnet-sdk-2.2=2.2.108-1
3.查看修改完的环境:
