Remarks
The ExchangeType property is typically used first to upload all the changes from several Subscribers to a Publisher, and then to download the changes to the Subscribers only after all the uploads have been completed.
BIDIRECTIONAL is the default. You should use a BIDIRECTIONAL synchronization unless you have a specific reason for separating the UPLOAD and DOWNLOAD phases.
