As far as I know, Normally we load related entities using LoadProperty in the context or use Include in the Linq query. There are several ways how to load navigation properties in EF.
•Eager loading (using Include)
Include is an example of eager loading. May be you should avoid using Include if it expands multiple detail rows on a master table row.
•Explicit loading by ObjectContext.LoadProperty
Explicitly loads an object related to the supplied object by the specified navigation property and using the default merge option. The LoadProperty method must be called to achieve explicit loading when you are using POCO custom data classes
