Can Entity Framework add many related entities with single SaveChanges()?

Question

I am writing many (20+) parent child datasets to the database, and EF is requiring me to savechanges between each set, without which it complains about not being able to fig

You don`t need to save changes every time if you use objects refernces to newly created objects not IDs:

var addItemTracking = new ItemTracking
{
    ...
}
_context.ItemTrackings.Add(addItemTracking);
var addInventoryTransaction = new InventoryTransaction
{
    itemTracking = addItemTracking,
    ...
};
_context.InventoryTransactions.Add(addInventoryTransaction);
...
_context.SaveChanges();
