Fundamental Question about saving data files on Hololens
I am sorry to keep asking this question or something similar but I have yet to find a satisfactory solution to this one. I am developing an Application based on Hololens. I have got to handle Unity as part of this process which presently supports C# 4.4 and no higher. I can add stuff to save XML files to HoloLens using just VS15 as the development platform. I could store and load them later using the HoloLens. However, when I went back to Unity to add more MonoBehaviour classes and change the infrastructure around, I found I was getting errors so that the 'building settings' could not progress. I have gone back to using standard file routines in a BackgroundWorker class except now I have a problem with opening KnownFolders which uses 'await' and 'async' commands. It seems to be a bit of a puzzle to me. I have OneDrive installed on HoloLens and I can share files with my PC but really don't know how to use it. I use the Windows Device Portal for uploading and viewing files and apps. It works great for a lot of stuff. I would like to see my saved data file on there and download it onto my PC later. If that were possible
Could anyone put me right on the best strategy to write and read data files here which is also compatible with Unity using the HoloLens please?
