When should you consider using eager loading in Entity Framework to retrieve related data?

Eager loading should be considered when dealing with complex object graphs, meaning scenarios where an entity has multiple related entities and navigating through them would lead to multiple database round-trips if lazy loading were used. Eager loading retrieves all related entities in a single query, which can reduce the number of database round-trips and improve performance in such scenarios. This approach is suitable when memory usage is not a significant concern, as it may lead to loading unnecessary data into memory.
