Which approach helps in reducing memory footprint in Entity Framework applications?

Lazy loading is a technique in Entity Framework where related entities are not loaded until they are explicitly accessed. This approach helps in reducing the memory footprint because it loads only the necessary data when it's needed, rather than loading all related entities upfront. Eager loading, on the other hand, loads all related entities along with the main entity, which can lead to increased memory usage. Explicit loading allows loading related entities on demand but still requires additional memory compared to lazy loading. Raw SQL queries bypass the Entity Framework's tracking mechanism and may not manage memory efficiently. Therefore, lazy loading is recommended for reducing memory footprint in Entity Framework applications.
