关于this.initializeComponent;

如何解决关于this.initializeComponent;

好的，所以我试图学习如何在UWP中制作应用程序， 而且我一直在努力使“图形教程”起作用。 （https://docs.microsoft.com/en-us/graph/tutorials/uwp?tutorial-step=1）

我已逐步按照该页面上的说明进行操作，并且 当我进入调试步骤时，它将在MainPage.xaml.cs上暂停，并带有 this.initializeComponent();

上的异常

异常消息对我没有太大帮助，

Windows.UI.Xaml.Markup.XamlParseException：'找不到与此错误代码关联的文本。 无法分配给属性“ Windows.UI.Xaml.ResourceDictionary.Source”，因为无法将类型“ Windows.Foundation.String”分配给类型“ Windows.Foundation.Uri”。 [Line：44 Position：86]'

现在，很明显，我在做错什么，因为这实际上是剪切粘贴的代码。但是我不知道那会是什么。并且由于本教程的所有后续部分都依赖于第一步正常运行，因此我无法继续进行下去。有什么想法吗？

这是MainPage.xaml.cs文件

解决方法

异常消息对我没有太大帮助，

在测试过程中，InAppNotification控件中出现问题，请打开程序包管理器控制台，并调用以下命令将Microsoft.Toolkit.Uwp.UI.Controls更新为7.0.0-preview2版本。例外会消失。

Install-Package Microsoft.Toolkit.Uwp.UI.Controls -Version 7.0.0-preview2
