Hi rbatistaole,
 
The graph on Code First entities should be about the same, but you'd be getting the EntityRelations from the MetadataStore.
 
Can you explain what exactly is the problem you are having?

No problem really. Instead i need to make use of the Manager.FindEntityGraph since the EntityRelations in the example was generated for the edmx. In code first how I get these relations?
thanks.

Like mentioned previously, using the MetadataStore:
i.e.
 
var span1 = new EntitySpan(typeof(Employee), EntityRelations.FK_Order_Employee, EntityRelations.FK_OrderDetail_Order);
 
var span1 = new EntitySpan(typeof(Employee), EntityMetadataStore.Instance.GetEntityRelation(typeof(Employee), Employee.EntityPropertyNames.Orders), EntityMetadataStore.Instance.GetEntityRelation(typeof(Order), Order.EntityPropertyNames.OrderDetails));
 
 
Silvio.

Ok, thanks. I think that the documentation is poor in this topic.
