c# - EF6, Circular dependency givs DbPpdateException -

i'm using entity framwork 6, code first.

i have entity team has list of members 1 member team leader.

public class team {     public virtual list<member> members { get; private set; }     public virtual member teamleader { get; private set; }      public team()     {         members = new list<member>();     }      public addmember(member member)     {         members.add(member);     }      public addteamleader(member teamleader)     {         teamleader = teamleader;         addmember(teamleader);     } } 

i want following throws dbupdateexception.

using(var uow = new unitofwork((new datacontext()))) {     var team = new team();     team.addmember(new member("adam"));     team.addteamleader(new member("david"));      uow.teams.add(team);     uow.complete(); } 

this works not nice , day write first version..

using(var uow = new unitofwork((new datacontext()))) {     var theteamleader = new member("david");     uow.members.add(theteamleader);     uow.complete();      var team = new team();     team.addmember(new member("adam"));     team.addteamleader(theteamleader);      uow.teams.add(team);     uow.complete(); } 

is possible create complete team members , leader , save database 1 savechanges?

the member table have foreign key team table , team table have foreign key member table it's circular dependency , therefore dbupdateexception.
