In NHibernate there is a merge function that does the following:

  • if there is a persistent instance with the same identifier currently associated with the session, copy the state of the given object onto the persistent instance
  • if there is no persistent instance currently associated with the session, try to load it from the database, or create a new persistent instance
  • the persistent instance is returned

Is this possible in EF? I mean this part : copy the state of the given object onto the persistent instance. And if i used ApplyCurrentValues it seemes to be as update behavior or not?
