C# – Entity Framework : explicitly loading a reference object

using (var context = new BreakAwayContext())
{
  var davesDump = (from l in context.Lodgings
                   where l.Name == "Dave's Dump"
                   select l).Single();
  context.Entry(davesDump)
         .Reference(l => l.PrimaryContact)
         .Load();
  davesDump.PrimaryContact = null;
  context.SaveChanges();
}
