Please anybody, let me know?

I am using EF with POCO. If I modify the POCO class & specify annotations using metadata, it works but as per the above approach (using metadatatype class alongwith a partial class for entity) it doesn't work. Any suggestions ?

public partial class Movie : IMovie

{

}

that implements an interface IMovie and then put the DataAnnotation attributes on the fields in the interface?

public interface IMovie

{

[Required]

object Title { get; set; }

...

Is there a data annotation that can handle arrays? Not sure on the best approach.
