We would like a new SetDirtyOnAdd property that works just like the SetDirtyOnEdit property for business objects.  If a user clicks to add a record and never actually enters any data, when they close the screen we don't want to show the save changes confirmation message.  Is this possible?

As mentioned above, if you have this need you can implement it yourself.  The GetFldState is replaced in ADO.NET by looking at the version of the field, which you can do just like you did in FoxPro.  All fields in ADO.NET have a buffer, this is how concurrency works.
