Remarks

An EntityReferenceStrategy is a combination of an EntityReferenceLoadStrategy, a MergeStrategy, and whether the load is synchronous or not.

The EntityReferenceStrategy is used when working with navigation properties. The Default strategy will lazily load the navigation property upon first access and preserve existing changes in cache. Other strategies allow you to turn off load altogether, or load the related entities every time the navigation property is accessed.

In mobile environments and Silverlight, the load is always performed asynchronously. In other environments you may choose to load related entities either synchronously or asynchronously.

The EntityReferenceStrategy may be set for an individual navigation property via its % NavigationEntityProperty.ReferenceyStrategy% or for the EntityManager as a whole with the EntityManager.DefaultEntityReferenceStrategy.
