i have baseentity : 

public class baseentity<t> {     public baseentity()     {         this.createddate = system.datetime.now;         this.updatetddate = system.datetime.now;     }     [system.componentmodel.dataannotations.key]     [system.componentmodel.dataannotations.required]     [system.componentmodel.dataannotations.schema.column("id")]     [system.componentmodel.dataannotations.schema.         databasegenerated(system.componentmodel.dataannotations.schema.databasegeneratedoption.identity)]     public t id { get; set; }     [system.componentmodel.dataannotations.required]     [system.componentmodel.dataannotations.schema.foreignkey("created_by")]     public virtual bonchaghwebapplication.models.core.user createdby { get; set; }     [system.componentmodel.dataannotations.required]     [system.componentmodel.dataannotations.schema.foreignkey("updated_by")]      public virtual bonchaghwebapplication.models.core.user updatedby { get; set; }     [system.componentmodel.dataannotations.required]     public datetime createddate { get; set; }     [system.componentmodel.dataannotations.required]     public datetime updatetddate { get; set; }     } }

and : 

[system.componentmodel.dataannotations.schema.table("app_user")] public class user:baseentity<long> {     public string username { get; set; }     public string password { get; set; }   }

and these 2 have 1 many relation, don't need collection on user side, record saved user , doesn't matter user save witch records
