The error stated that those entities (e.g. Firearm, FirearmDescription) have no key defined.

I can see you defined itemID. However, by convention this will not be used as the primary key unless you either

  1. Rename the field to FirearmId or,

  2. Add a [Key] attribute as below:

    [Key]
public int itemID {get; set;}

You may learn more about the convention here: https://msdn.microsoft.com/en-us/data/jj591583.aspx#Key
