从Entity Framework中的通用接口继承的实体

我有以下界面:

public interface IInitializable
{
    void Initialize ();
}

public interface IPersistXmlElementTo
{
    XmlElement ToXmlElement (XmlDocument document);
}

public interface IPersistXmlElement<T>:
    IPersistXmlElementTo,
    IInitializable
{
    T FromXmlElement (XmlElement element);
}

public interface IPersistXmlDocumentTo:
    IPersistXmlElementTo
{
    XmlDocument ToXmlDocument ();
}

public interface IPersistXmlDocument<T>:
    IPersistXmlDocumentTo,
    IPersistXmlElement<T>,
    IInitializable
{
    T FromXmlDocument (XmlDocument document);
}

public interface ICloneable<T>
    where T: ICloneable<T>
{
    T Clone ();
}

public interface ICopyable<T>:
    IInitializable,
    ICloneable<T>
    where T: ICopyable<T>
{
    T CopyFrom (T source);
    T CopyTo (T destination);
}

public interface IEntity
{
    long Id { get; set; }
    byte [] TimeStamp { get; set; }
    DateTime DateTimeCreated { get; set; }
    DateTime DateTimeModified { get; set; }
}

目前,所有实体类都从IEntity继承。我现在希望IEntity继承上面的接口。这意味着将IEntity转换为通用接口。类似的东西:

public interface IEntity<T>:
    IPersistXmlDocument<T>,
    IPersistXmlElement<T>,
    ICloneable<T>,
    ICopyable<T>,
    IInitializable
    where T: IEntity<T>

在从类继承时我遇到了EF问题,但到目前为止接口似乎工作正常。有什么值得注意的吗? EF中的任何特殊配置都需要从Entity: IEntity切换到Entity: IEntity<Entity>

事实证明,通用接口对EF无任何影响。
