What happens in Entity Framework when you query an entity that has already been retrieved in the current context?
- It fetches the entity from the database again, ignoring any previously retrieved instances.
- It merges the changes from the database into the tracked entity, ensuring data consistency.
- It returns the entity from the cache, avoiding a database round trip.
- It throws an exception indicating that the entity is already being tracked by the context.
Entity Framework utilizes its change tracking mechanism to detect changes made to entities within the context. When an entity is queried again, Entity Framework returns the already retrieved instance from the cache, ensuring data consistency and avoiding unnecessary database queries.
