- Para deshabilitar la carga diferida, establezca la propiedad LazyLoadingEnabled en false en la instancia de ObjectContextOptions devuelta por la propiedad System.Data.Objects.ObjectContext.ContextOptions

*Solución*:
- public AbcRestaurantsEntities(): base("name=AbcRestaurantsEntities")
  {
      this.Configuration.LazyLoadingEnabled = false;
  }
- Eliminar todos los decoradores 'virtual'
