Entity Framework class instantiation behavior

Question

I am facing a problem where my entity framework keeps behaving weirdly when I try to instantiate any class. I am trying to use the default usermanager behaviour

Answer 1

You don't have any foreign key to link AssociatedUser. Try adding a property to link Notification to ApplicationUser using foreign key. Like

public class Notification
{
    //rest of properties

    //change int to whatever type your primary key is in 
    //ApplicationUser class. I have Guid for example.
    public int ApplicationUser AssociatedUserId {get;set;}
}

Then try modifying configuration like this:

   modelBuilder.Entity<Notification>()
        .HasRequired(c => c.AssociatedUser)
        .WithMany(c => c.Notifications)
        .HasForeignKey(n=>n.AssociatedUserId);
