#If you use Windows Docker, dotnet restore might not work because of network issues.
#Docker for Windows uses the network adapter with the lowest Interface metric value.
#When this adapter is disconnected, your container cannot connect to the internet.
#To see if this is your problem as well:
#Get-NetIPInterface -AddressFamily IPv4 | Sort-Object -Property InterfaceMetric -Descending
#If yes, set your connected active connection to the lowest value:
#Set-NetIPInterface -InterfaceAlias 'Wi-Fi' -InterfaceMetric 20
