I am using a dataset to pull data from a DB. One of the fields in a row is NULL. I know this. However, the following vb.net code throws a StrongTypingException (in the autogenerated get_SomeField() method in the dataset designer):

If Not IsDBNull(aRow.SomeField) Then
'do something
End If

According to documentation and this question it should be fine.

edit: If aRow.SomeField is DBNull.Value Then also returns the same error. Argh.
