Question

I have entity framework setup and I have the following relationships setup:

• AdListing (AdListingID, Title, Details)
• AdListingLocation ( An AdListing can have multiple locations: AdListingID, LocationID)
• Location (LocationID, Country, City)

In EF I would like to return all AdListings where the City is “New York”

Keep in mind I would also like to load the AdListingLocation relationship (along with some others). In another post I learned I am not allowed to do manual joins if I am using .Include. How can I accomplish both?

var results = (from a in db.AdListings.Include("AdListingPhotos").Include("AdListingLocations")
               where a.AdListingLocations.Location.City = "New York"
               select a).ToList();

Answer 1

var results = from a in db.AdListings
              where a.AdListingLocations.Location.City == "New York"
              select a;

return results
       .Include(a => a.AdListingPhotos)
       .Include(a => a.AdListingLocations)
       .ToList();

To get the lambda syntax on Include just put this line:

 using System.Data.Entity;
