To push members down
  1. Position the caret at any of the type members that you want to push down.
  2. Choose ReSharper | Refactor | Push Members Down. The Push Members Down wizard opens:
    Refactorings__Push_Members_Down__dialog_box
  3. Select destination types from the list at the top of the wizard.
  4. In the Select members list, select members of the current type that you want to push down. Optionally, click one of the following buttons:
    • All Public to select all public members of the current type.
    • Dependent to select members that are referenced by any other previously selected members.
  5. For any member, select Make abstract (if applicable) to make the original member abstract and move its implementation to the newly created overriding member.
  6. Click Next. If no conflicts are found, the refactoring is performed immediately. Otherwise, resolve conflicts.
