You should be writing that NHibernate comparison, not fixing bugs (or even worse, sleeping!!!) :wink:

Of course I'm joking (maybe :wink:)... but anyway once you get that published I'm sure many customers are going to comment about the amazing support as being a huge asset for DO.

The bug is fixed.

The issue occurs, if type T having a reference property R is removing, but there is EntitySet<t> paired to R. E.g. it was impossible to upgrade from:

[Serializable]
  [HierarchyRoot]
  public class Person : Entity
  {
    [Key, Field]
    public long Id { get; private set; }

    [Field]
    [Association(PairTo = "Person")]
    public EntitySet<Address> Addresses { get; private set; }
  }

  [Serializable]
  [HierarchyRoot]
  public class Address : Entity
  {
    [Key, Field]
    public long Id { get; private set; }

    [Field]
    public Person Person { get; set;  }
  }

To:

[Serializable]
  [HierarchyRoot]
  public class Person : Entity
  {
    [Key, Field]
    public long Id { get; private set; }
  }

Workaround for now is to manually remove the table mapped to type T (i.e. for type Address in this case) before upgrade.
