  • For help with Xamarin please post in the Xamarin forums at http://forums.xamarin.com. That said, System.Data.SqlClient is not part of .Net Standard 2.0 and is not available to UWP apps. See https://docs.microsoft.com/en-us/dotnet/api/system.data.sqlclient.sqlconnection?view=netframework-4.7.1#Applies_to
