it's not a duplicate. it returns null after showing the open file dialog. but I cannot even see the open file dialog.

@mcferry Did you add entries to the entitlements file (not info.plist)?
For local debug you shouldn't need to do the capabilities and provisioning profile to see the dialog popup - but you do need to append entitlements file.

Also in case it's a typo - if you're adding code to code behind file you should use

FileResult? selectedFile = await FilePicker.Default.PickAsync();

and not FilePicker.PickAsync

(FYI the above line for me works on macOS to show the dialog. But unfortunately it always returns null after selecting files at this moment of time)
