XamlParseException thrown when repeatedly opening a control page.
Which version of the app?
WinUI 3 Gallery
Description
- Run the current build of WinUI 3 Gallery.
- In the navigation menu click "All" to display the grid of all controls.
- Click the NavigationView tile to display the NavigationViewPage
Repeat steps 2 and 3 several times (2 to 10 times usually) until a XamlParseException: 'XAML Parsing Failed.' exception is thrown within the generated (NavigationViewPage.g.i.cs) partial class InitializeComponent() method on the last line of this method:
' global::Microsoft.UI.Xaml.Application.LoadComponent(this, resourceLocator, global::Microsoft.UI.Xaml.Controls.Primitives.ComponentResourceLocation.Application);'
(see screenshot below)
This same XamlParseException has also been observed with the ViewboxPage following the same steps. This same XamlParseException has also been observed with the ViewboxPage following alternate steps clicking the Viewbox tile to open the ViewboxPage alternating with clicking almost anything else in the navigation menu. Again it happens after reopening the Viewbox page between 2 to 10 times.

Thanks for filing this bug @MarkBrainfire, I was also able to repro.
No idea why this happens, given that this didn't occur in the WinUI 2/XCG back then, I'm inclined to say this is a WinUI 3 issue. I'm not sure though if this is only happening when a debugger is attached/when we are running in debug or if the store version also exhibits this behavior.

@chingucoding The store version also crashes
The navigationview page easily reproduces.
