| > Similarly, byte[] properties that are configured as generated on add or update and marked as concurrency tokens are set up with the rowversion data type, so that values are automatically generated in the database.

| > Depending on the database provider being used, values may be generated client side by EF or in the database. If the value is generated by the database, then EF may assign a temporary value when you add the entity to the context; this temporary value will then be replaced by the database generated value during `SaveChanges()`. For more information, [see the docs on temporary values](xref:core/change-tracking/explicit-tracking#temporary-values). |
