        public DisposeExample(SchoolContext dataContext)
        {
            // Sets the data context
            _context = dataContext;
        }

        public void Example()
        {
            // Instantiates a DataStore object with datawindow: d_department.
            var datastore = new DataStore("d_department", _context);

            datastore.Retrieve();

            // This datastore has four records.
            int count = datastore.RowCount;
            Console.WriteLine("Retrieved Rowcount: {0}", count);

			//Resets the unmanaged resource in the DataStore.
            datastore.Dispose();
            try
            {
                count = datastore.RowCount;
            }
