with this code I got the message "System.Exception: Set property 'System.Windows.ResourceDictionary.Source' threw an exception," I am developing in Revit Api 2023

Version

5.2.1

Inizia con lo XAML WPF incorporato in TestView e riproduci l’eccezione ResourceDictionary.Source in Revit API 2023 con MaterialDesignThemes.Wpf 5.2.1. Verifica il pack URI referenziato e la disponibilità della risorsa; il lavoro è completato quando TestView viene caricato senza l’eccezione.
