Revision 13020: 2021-03-16

SQLServer which updates System.Data.SqlClient is superseded by Microsoft.Data.SqlClient. It is forced to update now to use Azure ActiveDirectoryIntegrated connection mode in MDrivenServer.

In other words: Before, the means to communicate with SQLServer was in System.Data - but Microsoft has abandoned that and everything (plus new stuff) is now in a Nuget library called Microsoft.Data.SqlClient. The switch was forced due to the AzureSQL connection string ability to set ActiveDirectoryIntegrated.
