So I am having a bit of an issue when I try to save related model data. I am adding the phoneBook sample to my current project for demonstration sake and when I try to save a person phone number i get the following error....

Not sure why ICollection of Phones in the person entity is not considered a navigation property..

Could be the end of the day has the brain tired..
