Does anyone know of any tweaked version of POCO T4 template that generates interfaces along with classes? i.e. if I have Movie and Actor entities in .edmx file, I need to get the following classes and interfaces.

interface IMovie
{
    string MovieName { get; set; }
    ICollection<IActor> Actors { get; set; } //instead of ICollection<Actor>
}

class Movie : IMovie
{
    string MovieName { get; set; }
    ICollection<IActor> Actors { get; set; } //instead of ICollection<Actor>
}

interface IActor
{
    string ActorName { get; set; }
}

class Actor
{
    string ActorName { get; set; }
}

Also, just in case I write my own entities, does POCO proxies(I need them for lazy loading) work with the interface declarations as shown above?
