Gets a value indicating whether this property is used as a concurrency token. When a property is configured as a concurrency token the value in the database will be checked when an instance of this entity type is updated or deleted during SaveChanges() to ensure it has not changed since the instance was retrieved from the database. If it has changed, an exception will be thrown and the changes will not be applied to the database.
