Question

$SQLconnection = New-Object System.Data.SqlClient.SqlConnection
$SQLconnection.ConnectionString = \"Server = MySQLservername\\MSSQLSERVER; Database = \"MYSQLDB\"; In         


        

Answer 1

I had the same error and changed appsettings.json to

"DefaultConnection": "Server=localhost; database=my-vue-starter-new;MultipleActiveResultSets=true;User Id=SA;Password=myPassword;"

important on linux the server is localhost and the Id automatically became SA

another thing may cause to gthat issue if you didn't configure mssql, enabled the tcpport to 1433 if not do it and try to connect again.
