左连接与联结表

Question

我有以下表格： -

- Visit
- Vehicles
- VehicleVisits (junction table of the above two)

我想要一个linq查询以使用VehicleVisits离开联接访问表 像这样：

from workOrder in dbContext.WorkOrders 
join visit in dbContext.Visits on workOrder.VisitID equals visit.ID         
from v in visit.Vehicles into leftJoin
from  leftJoin1 in leftJoin.DefaultIfEmpty()

但这个查询不正确
我该怎么办？
