Hi
I'm working on a Windows Phone 8 app and am not having any luck creating a zip (renamed to .ppsx) that PowerPoint will open. I'm using ~98% the same code that works with my Windows 8 app utilising System.IO.Compression to create a zip. Since that library is not available in WP8 I gave SharpCompress a go. Is there a trick or certain compression format that I need to use to create a valid Office Open XML document? If I extract and re-zip my SharpCompress created archive using Windows File Explorer, PowerPoint opens the file no problems.
