Oh, sorry.
I forgot to add the classes:
EntityBase, just to avoid adding Version and Id in each entity
abstract public class EntityBase
{
public virtual Guid Id { get; protected set; }
public virtual int Version { get; set; }
// Two entities are considered equal if their Ids are the same
public override bool Equals(object obj)
{
if (obj == null)
return false;
var other = obj as EntityBase;
if (other == null)
return false;
if (Id.Equals(Guid.Empty))
return ReferenceEquals(this, obj);
return Id.Equals(other.Id) && Version == other.Version;
}
public override int GetHashCode()
{
return Id.GetHashCode();
}
}
public abstract class RegistryBase : EntityBase
{
// -- additional properties omitted --
public virtual short Priority { get; protected set; }
}
public abstract class Case : RegistryBase
{
// -- additional properties ommited --
public virtual IList<Specimen> Specimens { get; set; }
}
