Parameters

masterForm
The Master Form object to be deleted.

Remarks

The source code for this interface implementation class is available at <INSTALLDIR>\Examples\Forms\DotNet\AutoMasterFormsRepository.

The masterForm file will be deleted and cannot be restored. If the user want to do different action he can inherit this class and override this method or he can do his own implementation of IMasterFormsCategory. Be advised to have a back up copy of all Master Forms if this used this class, in case you have deleted the wrong Master Form.

There is no need to call DiskMasterFormsRepository.Refresh since the repository that this Master Form belongs will be updated with this deletion.
