c# - Entity Framework Query for inner join

Question

What would be the query for:

select s.* from Service s 
inner join ServiceAssignment sa on sa.ServiceId = s.Id
where  sa.LocationId = 1

in entity framework?

This is what I wrote:

 var serv = (from s in db.Services
                join sl in Location on s.id equals sl.id
                where sl.id = s.id
                select s).ToList();

but it's wrong. Can some one guide me to the path?

Answer 1

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
