Entity Framework: I set the foreign key, SaveChanges then access the navigation property, but it doesn't load the related entity. Why not?

Question

I am using this Entity class with Entity Framework 5 Code First:

public class Survey
{
    [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public i         


        

Answer 1

You need to define all the properties on the Survey class as virtual to enable lazy-loading.
