entity framework - How to update an object in the object context including its relationships -

i update object in object context data data source using code:

 public class project     {       public string id{get;set;}       public string name{get;set;}     }  public class people     {        public string id{get;set;}       public string name{get;set;}       public ilist<project> projectlist{get;set;}     }   ((system.data.entity.infrastructure.iobjectcontextadapter)orm).objectcontext.refresh(             system.data.objects.refreshmode.storewins, people); 

it updates people not projectlist(navigation properties),so question is: how update object including relationships?

as far know can't automatically that, refresh works on primitive properties of single object. if need additional refreshes need loop through objects , refresh each one.

naturally better approach reload entire graph eager loading, if don't need keep objects since you're refreshing them.
