Hi, I'm trying to do a one-to-one relationship, with the navigation property just on one side.
public class User {
public int UserId { get; set; } //PK
public int RankId { get; set; } //FK
public virtual Rank { get; set; } //Navigation
}
public class Rank {
public int RankId { get; set; }
}
Configuration:
public class RankConfiguration : EntityTypeConfiguration<Rank>
{
public RankConfiguration()
{
HasKey(e => e.RankId);
Property(e => e.RankId)
.HasDatabaseGeneratedOption(DatabaseGeneratedOption.None);
}
}
public class UserConfiguration : EntityTypeConfiguration<User>
{
public UserConfiguration ()
{
// PK
HasKey(e => e.UserId);
Property(e => e.RankId)
.IsRequired();
HasRequired(e => e.Rank)
.WithRequiredDependent()
.WillCascadeOnDelete(true);
}
}
For what I see (and for the little I know), db is correctly generated, but I get this error:
A dependent property in a ReferentialConstraint is mapped to a store-generated column. Column: 'UserId'.
I have no idea why and what is wrong .. any help? many thanks in advance

Hi,
This error says that UserId is used as foreign key (= dependent property) in some relation which is not allowed because only properties with StoreGeneratedPattern.None can be used as foreign key. Please try to check it.
If you have any other problem, please let me know.
