Joining two repository from two different database #966

Hi-

I was trying to use Join using two repositories from two different databases :

      var Xlist = _xxxxxxx.GetAllList(o => o.CreationTime >= givenDate).GroupBy(u => new { u.SomeId, u.SomeId2 })
                                              .Select(group => new {Column1 = group.Key.SomeId, SomeId2 = group.Key.SomeId2, Column2 = group.Count(o => o.Deid != null), Column3 = group.Count(o => o.IsProcessed == true), RejectedCount = group.Count(o => o.IsRejected == true), ToTotalFileCOunttal = group.Count() })
                                             .Join(xxxxxxxx.GetAllList(),u => u.Column1, p => p.Id , (u, p) => new { u.Column1,u.SomeId2,u.Column2,u.Column3,u.RejectedCount,u.ToTotalFileCOunttal, p.table2Id })
                                              .ToList();

I am getting the below error :
