c# - Using FileOpenPicker app contract Hololens 2 with Unity development

Question

Similar to this post I am trying to implement FileOpenPicker into my hololens 2 app. However, I am doing this through the Mixed Reality Toolkit in unity and have been having some troubles finding out how to set up the contract within the app.

I know the post I linked above directs you to FileOpenPicker which is what I have been trying to do but I'm a bit confused about the samples they have and how to do that within unity C#.

Any recommendations on how to get this working would be a big help. Thanks!

There is also This post that helps with how to use FileOpenPicker but it's directed at standalone UWP apps and not something built in unity.

Answer 1

So for anyone who stumbles across this post, as of 2/8/2021 using FileOpenPicker with no other installed apps on the Hololens 2 doesn't work.

It took me forever to find this post but here's a partial answer Open local data path with FileOpenPicker

So to make a TL;DR about that post. FileOpenPicker DOES work on Hololens, however, it works through externally installed File picker like OneDrive.

I don't know why I didn't find this post sooner until I went down every avenue to figure it out.

EDIT: I managed to solve my issue over on THIS POST if there is anyone stumbling across this issue hopefully that helps.
