[MEnzio]

hello there

i have a entity like this

 [Table(nameof(SiteSettings), Schema = "Admin")]
    public class SiteSettings : BaseModel
    {
        public SiteSettings()
        {
            UniqueId = Guid.NewGuid();

        }
        [Key]
        public override Guid UniqueId { get; set; }
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int Code { get; set; }
        public SmtpConfig Smtp { get; set; }
        public bool EnableEmailConfirmation { get; set; }
        public bool EnablePhoneConfirmation { get; set; }
        public TimeSpan EmailConfirmationTokenProviderLifespan { get; set; }
        public TimeSpan PhoneConfirmationTokenProviderLifespan { get; set; }
        public int NotAllowedPreviouslyUsedPasswords { get; set; }
        public int ChangePasswordReminderDays { get; set; }

        public string AttahmentFileRoot { get; set; }
        public bool HttpsEnabled { get; set; }
   
    }

and the SmtpConfig class is

[Owned]
    public class SmtpConfig
    {

        public string Server { get; set; }
        public string Username { get; set; }
        public string Password { get; set; }
        public int Port { get; set; }

        public string PickupFolder { get; set; }
        public string FromName { get; set; }
        public string FromAddress { get; set; }
    }

when im try ing to add migrations i got navigation propert error

An error occurred while accessing the Microsoft.Extensions.Hosting services. Continuing without the application service provider. Error: Navigation property 'Smtp' on entity type 'SiteSettings' is not virtual. UseLazyLoadingProxies requires all entity types to be public, unsealed, have virtual navigation properties, and have a public or protected constructor.
