In case anyone s interested in the Method syntax  if you have a navigation property  it s way easy   db Services Where s  gt s ServiceAssignment LocationId    1     If you don t  unless there s some Join   override I m unaware of  I think it looks pretty gnarly  and I m a Method syntax purist    db Services Join db ServiceAssignments        s   gt  s Id       sa   gt  sa ServiceId         s  sa    gt  new  service   s  asgnmt   sa    Where ssa   gt  ssa asgnmt LocationId    1   Select ssa   gt  ssa service

from s in db Services join sa in db ServiceAssignments on s Id equals sa ServiceId where sa LocationId    1 select s   Where db is your DbContext  Generated query will look like  sample for EF6    SELECT  Extent1   Id  AS  Id         -- other fields from Services table FROM  dbo   Services  AS  Extent1  INNER JOIN  dbo   ServiceAssignments  AS  Extent2      ON  Extent1   Id     Extent2   ServiceId  WHERE  Extent2   LocationId    1

You could use a navigation property if its available  It produces an inner join in the SQL   from s in db Services where s ServiceAssignment LocationId    1 select s
