@scottkuhl If you set your target to 18362 does that fix?

[scottkuhl]

Yes, that does fix the issue. Is 1903 a requirement for Shell on Windows? Or this is just a bug?

@scottkuhl I would say it's a bug

The NavigationView that shell is based on works on version 1809 (SDK 17763) so it should work with the target frameworks you've specified

having the same issue on UWP startup after i upgraded xamarin form from 3.4.0.1008975 to 4.8.0.1269, unfortunately VS2017 forced the UWP project to use 17763 even i changed to 18362 by editing the project file backdoor.
