 Raised when the repository `Save` method is called and before the entity has been persisted. The notification contains an `Entity` property with `Before` and `After` inner properties. These properties provide access to a copy of the currently persisted entity (or null if a new entity) and the updated entity that´s saved.
 Changes can be made to the `After` entity and they will be persisted as part of the save operation. If the `Cancel` property of the notification is set to `true` then the save operation will be canceled and no changes will be saved.
