Entity Framework: Find EntityKey Values for One-to-Many
In EF, it is possible to write the following line:

    orderLine.OrderReference.EntityKey.EntityKeyValues[0].Value

Wich results in the ID of the associated OrderReference.

What would be the solution if I wanted to know the ID's of the orderLines associated with an order?
