EF 4.1 RC Many to many relationship in EF CF

Question

I have two entities with many to many relationship like this:

class author
{
  public int AuthorID{get;set;}
  public string Name{get;set;}
  public virtual ICol         


        

Answer 1

I don't think EF allows you to have a separate Id in many-to-many junction tables.

The alternative is just mapping BookAuthor as an entity.

On a side note, NHibernate supports this construct using an idbag
