Script Task code that has worked for years, no longer works in SSIS for SQL 2016

Hi 

This code :

            OleDbDataAdapter da = new OleDbDataAdapter();
             DataTable dt = new DataTable( );

            da.Fill(dt, Dts.Variables["User::Versions"]);

Has worked for years, but now throws an error that the object type is not ADODB.RecordSet???

How do we make it work now?

Any help much appreciated
