If I have two tables; Drivers keyed by DriverId and Trips with foreign keys DriverId and CoDriverId, and I want to find all trips where a driver was either the driver or co-driver I could code this in Transact-SQL as

select d.DriverId, t.TripId 
from Trips t inner join Drivers d 
on t.DriverId = d.DriverId or t.CoDriverId = d.DriverId

How could this be coded as a LINQ query?
