Hello.
This app was working fine, it was populating the font, and the numbers coming from my View Model, but for some reason it broke, I notice that Visual Studio sometimes acts stupid (especially on UWP development)
could somebody help me resolve this issue *anonymous user*
for some reason, it can't find my VM.

In addition, I found the listView didn't display, did you implement INotifyPropertyChanged interface for properties in Note and NoteBook model? About "for some reason, it can't find my VM.", under what unexpected behavior you think "it can't find your VM"?

by the way I have my project here, if you could please help me fix the speech problem

2019-12-27T07:47:54.637+00:00 Do you mean you just drop down the CombBox, sometimes it will turn black? I tested many times, but didn't reproduce. In addition, about the "Cannot find VM", it just the compiler issues, you can ignore it and generally when you rebuild the project, it will disappear.
