Question

I’m creating a database in EF4.1 Code First. I’ve got a one-to-many relationship of health forms with health dependents. A health form has 0-5 dependents. When I create the healthform, the dependents table is created for me by using

modelBuilder.Entity<BenefitsForm>().HasMany(t => t.Dependents).WithOptional().WillCascadeOnDelete();

However, when I use the retrieve method:

return context.BenefitsForm;

it does not display the Dependents table join, only the BenefitsForms. How can I get it to show the BenefitsForm table linked with Dependents table?

Answer 1

One way is to use the Include() method – http://msdn.microsoft.com/en-us/library/bb738708.aspx

return context.BenefitsForm.Include("Dependents");

Another way is to enable LazyLoading on your context – http://msdn.microsoft.com/en-us/library/system.data.objects.objectcontextoptions.lazyloadingenabled.aspx

yourContext.ContextOptions.LazyLoadingEnabled = true;
