BulkInsertOrUpdate doesn't return Identity when no insert or update happen

[ksbecker]

I have a table of recipient addresses. I only want to insert an address once so I'm using the BulkInsertOrUpdate method and am specifying the columns to check against deduping in the BulkConfig. I don't have any other properties that would change as a result. However I want to get back all of the addresses with their identity regardless of whether they were updated or inserted. Below is the call to the method. Is there a better way of handling this?

dataContext.BulkInsertOrUpdate(recipients, new BulkConfig
{
    UpdateByProperties = ["Address1", "Address2", "City", "State", "Zip5"],
    SetOutputIdentity = true,
});
