WCF RIA Services: Loading associated entities

Just a quick note to self: when you want to load associated entities in query you have to do it at two places,

1- in the query itself using the Include method

public IQueryable<MasterEntity> GetItems()
{
    return this.ObjectContext.MasterItems.Include("DetailsEntities");
}

2- in the associated metadata class

 internal sealed class MasterEntityMetadata
    {
        private  MasterEntityMetadata()
        {
        }

        [Include]
        public EntitySet<DetailsEntity> DetailsEntities;

    }
