Entity Framework 4.1 InverseProperty Attribute

Question

Just wanted to know more about RelatedTo attribute and I found out it has been replaced by ForeignKey and InverseProperty attributes i

Answer 1

ForeignKey attribute pairs FK property with navigation property. It can be placed either on FK property or navigation property. It is equivalent of HasForeignKey fluent mapping.

public class MyEntity
{
    public int Id { get; set; }

    [ForeignKey("Navigation")]
    public virtual int NavigationFK { get; set; }

    public virtual OtherEntity Navigation { get; set; }
}

InverseProperty is used for defining self referencing relation and pairing navigation properties on both ends. Check this question for sample.
