I created a new .Net core console project using the following command.
dotnet new console
dotnet run
However, Install-Package System.Data.SqlClient
got the following error?
PS C:\temp> dotnet new console The template "Console Application" was created successfully. Processing post-creation actions... Running 'dotnet restore' on C:\temp\temp.csproj...
