EF: Validation failing on update when using lazy-loaded, required properties

Question

Given this extremely simple model:

public class MyContext : BaseContext
{
    public DbSet Foos { get; set; }
    public DbSet Bars { g         


        

Answer 1

I know it's a bit late... However, ill post this here. Since i too got horribly annoyed with this. Just tell EF to Include the required field.

Notice the SMALL change

using (var context = new MyContext())
{
    var foo = context.Foos.Include("Bar").Find(id);
    foo.Data = 2;
    context.SaveChanges(); //Crash here
}
