Question : Hololens pickers
Concerning this page:
https://docs.microsoft.com/fr-ch/windows/mixed-reality/app-model#known_folders
Why is HoloLens only supporting FileOpenPicker ? And is it still true that no pickers comme with the OS ? Because there is a file explorer and I first supposed that those information were out dated..
I need to pick a folder in which my app will try to read files. I set the Documents Library capability in the XML and was hoping that I could pick a folder in it..
What would be the simplest/ best way to achieve this ?
Thanks for your help

the post above helped me making the FileOpenFicker work. To make it short, the picker need to run on the UI thread. Then I had to make my calls on the app thread otherwise it had no effect.
Then I tried with FolderPicker, and it worked. I think this is due to the RS4 which brough a file explorer.
Posting this response in hope It will help other people asking themself those questions
