Update 12.31.2021: This project has to be downgraded to Microsoft.Data.SqlClient 3.0.1, because of the (unwanted) breaking changes in 4.0.0, which forces you install a certification in SQL Server, or put encrypt=false.
Updating Microsoft.Data.SqlClient is not recommended at this time.
DataJuggler.Net6 is a core component of several Data Juggler projects including DataTier.Net, DB Compare and XML Mirror.
