Actually, the Dev Guide has this code:
' Wrapper method for GetCurrentDataSet that casts the DataSet to EmployeeDataSet
Public Function GetDataSet() As EmployeeDataSet
   Return CType(Me.GetCurrentDataSet(), EmployeeDataSet)
End Function
Note the method is GetDataSet(), not GetCurrentDataSet(), so there is no need for the Overrides keyword since there is no method named GetDataSet() in mmBusinessObject.
