Die App wird in der AppHostBuilderExtension<\/strong> konfiguriert, welche Ihr unter “Hosting” im Projektordner findet. Um alle Features der App-Vorlage zu initialisieren, muss die Methode “ConfigureApp” in der “MauiProgram.cs” mit angeh\u00e4ngt werden.<\/p>\n\n\n\n

The following methods are executed.<\/p>\n\n\n\n

Singleton & Transient<\/h3>\n\n\n\n
Basically, we differentiate between the two types of registration mentioned. All ViewModels<\/strong> and Views<\/strong> that are or should be available over the app lifecycle are registered as a singleton<\/strong>. This applies to all main pages.<\/p>\n\n\n\n
Alle anderen Elemente, welche nur solange “Leben” sollen, wie diese ben\u00f6tigt werden, werden als Transient<\/strong> registriert. All solche Elemente werden, sobald ben\u00f6tigt, erstellt und nach Gebrauch wieder freigegeben (GC).<\/p>\n\n\n\n
For new View & ViewModels<\/h3>\n\n\n\n
Important! If you add new Views and\/or ViewModels, you must configure or make them known in the AppHostBuilderExtension<\/strong>. Depending on the type, the following methods are available for this.<\/p>\n\n\n\n
    \n
  • RegisterMainViewModels \/ RegisterMainViews:<\/strong> For all main page\/viewmodels<\/li>\n\n\n\n
  • RegisterPageViewModels \/ RegisterPageViews<\/strong>: F\u00fcr alle Views & ViewModels im “Pages”-Ordner<\/li>\n\n\n\n
  • RegisterModalViewModels \/ RegisterModalViews: <\/strong>F\u00fcr alle Views & VIewModels im “Modal”-Ordner<\/li>\n\n\n\n
