Loading Related Data
https://docs.microsoft.com/en-us/ef/core/querying/related-data
- Eager loading means that the related data is loaded from the database as part of the initial query.
- Explicit loading means that the related data is explicitly loaded from the database at a later time.
- Lazy loading means that the related data is transparently loaded from the database when the navigation property is accessed. Lazy loading is not yet possible with EF Core.
