Reactive Ui Dynamic Data, ui refresh problem

Question

I have small problem with using Dynamic Data and Reactive UI. I am trying to make an UWP app. My problem is that my View component does not refresh after updating ViewModel property. I am following the ReactiveUI docs and also the examples which are at the end of the site. The component I am trying to update cames from Windows Community Toolkit. I am adding new photos to app and the add them to gallery. My code: gist

What I tried:

• Catching exception in the Subscribe but nothing shows up
• Removing the scheduler and also trying other
• Trying ObservableCollection
• using out var photos instead of out _photos

Answer 1

Why using Reactive UI in the UWP app? UWP has it's own mechanism to update UI whenever your ViewModel changes. And I found it very easy.
