yes, that makes sense, although I didn't do it that way because
System.Data.OleDb was on a standard assembly, whereas GDA# are in GTK#,
which is outside of the so-called standard assemblies.
If there were any way to make use of the GDA# without depending on some
of the GTK# things (GLib), it would make a lot of sense.

yes, it will be much much easier, and given that the System.Data.OleDb
is already implementing the correct classes and in C#, in most cases it
will be just a matter of doing a wrapper, which as you say, is a lot
much easier.
