How to use interface properties with CodeFirst

Question

I have the following entities:

public interface IMyEntity
{
    [Key]
    int Id { get; set; }
    IMyDetail MyDetail { get; set; }
    ICollection

I've had the same problem and found a solution just like Nathan, but you can even take it one step further and have the properties named the same (here Extensions and IAddress.Extensions), by explicitly defining the interface:

public interface IAddress
{
    string Address { get; set; }
    IEnumerable Extensions { get; set; }
}

public interface IAddressExtension
{
    string Key { get; set; }
    string Value { set; }
}

[Table("AddressExtensions")]
public class AddressExtension : IAddressExtension
{
    [Key]
    public string Id { get; set; }
    public string Key { get; set; }
    public string Value { get; set; }
}

[Table("Addresses")]
public class Address : IAddress
{
    [Key]
    public string Id { get; set; }
    public string Address { get; set; }

    public IEnumerable Extensions { get; set; }

    [NotMapped]
    IEnumerable IAddress.Extensions
    {
        get { return Extensions; }
        set { Extensions = value as IEnumerable; }
    }
}

Code First ignores the interface-property and uses the concrete class, while you can still access this class as an interface of IAddress.
