Answer 1

If you got Only primitive types or enumeration types are supported in this context. because of using navigation property - consider adding foreign key property directly to the entity (maybe only with getter) and use it as Ladislav Mrnka proposed.

Answer 2

Try this:

context.People.AddOrUpdate(p => new { p.FirstName, p.LastName }, people);
