[Bug]: UWP app won't build due to certain views not being recognised

[AlexanderBlackman]

Describe the bug 🐞

Tried to build UWP app.
Build failed, due to
XDG0008 The name "DirectAuthView" does not exist in the namespace "using:Camelotia.Presentation.Uwp.Views". Camelotia.Presentation.Uwp D:\Downloads\Camelotia-main (2)\Camelotia-main\src\Camelotia.Presentation.Uwp\Views\AuthView.xam
The 'missing' files do exist, and they all render properly in Visual Studio 22.
The Avalonia and WPF example work without any issue.
