Linq到SQL dbml设计文件缺少新字段

我用一个新字段更新了数据库 HasPaebreak 我可以在dbml设计界面中看到它。但当我看这个类时,我并没有看到新的数据库字段。我需要删除这个文件还是手动更新?

设计表面。

[global::System.Data.Linq.Mapping.TableAttribute(Name="dbo.TemplateRelations")]
    public partial class TemplateRelation : IDatabaseEntity, INotifyPropertyChanging, INotifyPropertyChanged
    {
        
        private static PropertyChangingEventArgs emptyChangingEventArgs = new PropertyChangingEventArgs(String.Empty);
        
        private long _Id;
        
        private System.DateTime _Added;
        
        private System.Nullable<System.DateTime> _Modified;
        
        private System.Nullable<System.DateTime> _Deleted;
        
        private bool _IsDeleted;
        
        private bool _Frozen;
        
        private string _ReferenceText;
        
        private System.Nullable<int> _TemplateRelationTypeId;
        
        private long _RelatedTemplateId;
        
        private long _TemplateId;
        
        private EntityRef<Template> _Template;
        
        private EntityRef<Template> _Template1;
        
        private EntityRef<TemplateRelationType> _TemplateRelationType;
