Here is my repository method

//Coroutine Iterator

public IEnumerable<INotifyCompleted> CreateJobHistory(Member member)

{

     var localInfoOp = Manager.LocalInfos.ExecuteAsync();

     yield return localInfoOp;

//Get first LocalInfo.NextJobHistRef and increment by 1

    LocalInfo localInfos = localInfoOp.Results.First<LocalInfo>();

    int nextRefNo = localInfos.NextJobHistRef;

    localInfos.NextJobHistRef = nextRefNo + 1;

    List<Entity> changedEntities = new List<Entity>();

    changedEntities.Add(localInfos);

    var saveOp = Manager.SaveChangesAsync(changedEntities);

    saveOp.Completed += (sender, args) =>{

    if (args.CompletedSuccessfully){

    }

    else

// ////Create a new JobHistory

   JobHistory newJob = new JobHistory{

       SocSecNo = member.SocSecNo,

       RefNo = nextRefNo,

       Member = member

   };

   yield return Coroutine.Return(newJob);
