We make extensive use of System.IO.Packaging in our PC product to manage XLSX files. Packaging is really just a ZIP system that uses streams instead of files for all its intermediate work.
I'm trying to move this to iOS using Xamarin. System.IO.Packaging is supported by Mono's WindowsBase, am I correct in thinking that this is not supported on the Mac/iOS?
If that is correct, can someone suggest a replacement? Building a XLSX file is simple enough, we don't really use anything special in Packaging except for its iteration methods. Is the a simple way to iterate over the components of a folder hierarchy that works under Xamarin iOS?
