Overloads

AttachRange(Object[]) AttachRange(Object())

Begins tracking the given entities in the Unchanged state such that no operation will be performed when SaveChanges() is called.

A recursive search of the navigation properties will be performed to find reachable entities that are not already being tracked by the context. These entities will also begin to be tracked by the context. If a reachable entity has its primary key value set then it will be tracked in the Unchanged state. If the primary key value is not set then it will be tracked in the Added state. An entity is considered to have its primary key value set if the primary key property is set to anything other than the CLR default for the property type.
