To Delete a DAC Item from a Project

To remove changes to an existing data access class from a project, perform the following actions:
  1. Open the customization project in the Customization Project Editor. (See To Open a Project for details.)
  2. Click Data Access in the navigation pane to open the Customized Data Classes page.
  3. In the page table, select the item to be deleted.
  4. On the page toolbar, click Delete Row.
  5. On the page toolbar, click Save to save the changes to the customization project.
If you added a bound custom field to an existing data access class, the platform includes the DAC and Table items for this class in the customization project.
Note: The Table item contains a description of custom columns added to a database table for bound custom fields created in the appropriate data access class.
After you publish the customization project at least once, the database schema is changed. Changes to the database schema aren't deleted when you delete the DAC and Table items and publish the project. You have to remove the changes manually.

You can delete a DAC or Table item (or another item) from the customization project on the Edit Project Items page of the Customization Project Editor. (See To Delete Items from the Project on the Edit Project Items Page for details.)
