.NET Core配置多版本

1、查看dotnet當前使用的環境、sdk環境、已安裝的.NET
dotnet --info
Base Path: /usr/share/dotnet/sdk/2.2.300/
.NET Core SDKs /usr/share/dotnet/sdk
.NET Core runtimes installed: /usr/share/dotnet/shared/Microsoft.AspNetCore.All
2、做軟連接
新版本的路徑軟鏈接到當前版本路徑下
ln -s /usr/local/src/shared/Microsoft.AspNetCore.App/3.1.4 /usr/share/dotnet/shared/Microsoft.AspNetCore.App/3.1.4
ln -s /usr/local/src/shared/Microsoft.NETCore.App/3.1.4 /usr/share/dotnet/shared/Microsoft.NETCore.App/3.1.4
ln -s /usr/local/src/sdk/3.1.300/ /usr/share/dotnet/sdk/3.1.3
