Remarks
This method resets personalization data in the underlying data store, based on the PersonalizationStateInfo objects contained in the collection. You can use this method to selectively delete a mixture of shared and per-user data based on the collection's contents. SharedPersonalizationStateInfo objects indicate that shared data for a page will be reset; UserPersonalizationStateInfo objects indicate that per-user data for a specific page will be reset.
Note
This method does not guarantee that all resets occur within a single transaction because the collection points to random sets of personalization data.
It is not an error for the collection to contain objects that reference nonexistent data.
