Answer 1

Il dit clairement qu'il ne peut pas trouver le usercontrol dans cet espace. Alors s'il vous plaît vérifiez que vous l'avez dans le bon NameSpace.

Si ce n'est pas le cas, veuillez ajouter plus de détails à la question.

Answer 2

UserControl1 n'existe pas dans le bout de code que vous avez signalé. Il vous manquera une définition de xmlns: * au début de votre fichier xaml, mais sans plus de détails, nous ne pouvons rien faire pour vous aider. * Ceci spécifie l'espace de nommage et l'assemblage du code d'espace de noms, que vous utilisez ensuite pour référencer votre commande usercontrol.

xmlns:xyz="clr-namespace:Namespace.Path.To.My.Control;assembly=MyAssembly" 

et:

<xyz:UserControl1 Name="blah" />
