Microsoft.UI.Xaml.Markup.XamlParseException: 'XAML parsing failed.'

occuring at InitializeComponent(), which isn’t telling much, however the Xaml file is pretty simple.

In the generated file the respective line is :

global::Microsoft.UI.Xaml.Application.LoadComponent(this, resourceLocator, global::Microsoft.UI.Xaml.Controls.Primitives.ComponentResourceLocation.Application);

I modified a little bit the chart control properties and now GetForCurrentView() isn’t playing a role here. The LoadComponent() failed.

Can I find more info than “Xaml parser failed” ?

That is correct. I’m going to close this issue since the 3rd party control library is not currently compatible with WinUI 3.
