Answer 1

は（あなたができることに注意してください」DefaultIfEmptyに参加しますwhereがクエリを完了するためにselectに従わなければならないので、T）where句の後intoを使用します。

model.ListManagerReviewerMapping = (from a in wallet.OM_Employee 
            join m in wallet.APPR_ManagerMapping.Where(x => x.ManagerId == Context.UserId.Value) 
            on a.AssociateId equals m.AssociateId into MM 

            from leftjoinresult in MM.DefaultIfEmpty() 
            where a.CompanyId == Context.CompanyId && (a.TermStatus == "L" || a.SeparationDate > DateTime.Today) 
            select new ManagerAndReviewerMappingModel.ManagerAndReviewerMapping() 
            { 
             Photo = (photoUrl + "?AssociateCode=" + a.AssociateCode), 
             AssociateId = a.AssociateId, 
             AssociateCode = a.AssociateCode, 
             AssociateName = a.AssociateName 
            }).ToList();

//Remove brackets and .ToList(); 
model.ListManagerReviewerMapping = from a in wallet.OM_Employee 
           join m in wallet.APPR_ManagerMapping 
           on a.AssociateId equals m.AssociateId 
           where m.ManagerId==Context.UserId.Value **into** MM 
           from leftjoinresult in M.DefaultIfEmpty() 
           where a.CompanyId == Context.CompanyId && (a.TermStatus == "L" || a.SeparationDate > DateTime.Today) 
           select new ManagerAndReviewerMappingModel.ManagerAndReviewerMapping() 
           { 
            Photo = (photoUrl + "?AssociateCode=" + a.AssociateCode), 
            AssociateId = a.AssociateId,
