EF Code First forced eager loading

Question

I'm using EF 5 with Code First. I have a class that I want to always eager load some properties. I removed the virtual keyword but it's not eager loading:

public class Person
{
   public ICollection<Email> Emails { get; set; } 
   public Profile Profile {get;set;}
}

So by turning off lazy loading, it won't auto eager load right? If so, how do I archive that without using Include()?

Thanks!

No, turning off lazy loading by removing the virtual keyword will not automatically enable eager loading. You have to Include the related Entity or Collection like so:

var personWithProfile = ctx.People.Include(x => x.Profile).First();
var personWithProfileAndEmails = ctx.People.
                                           .Include(x => x.Profile)
                                           .Include(x => x.Emails)
                                           .First();
