C# 在WPF中创建Windows.UI.Composition.Compositor实例抛出0x80070005访问被拒绝

我正在尝试从WPF项目中使用Windows.UI.Composition API。 这似乎是可行的

但是，在新项目中使用它会引发异常：

System.UnauthorizedAccessException
  HResult=0x80070005
  Message=Access is denied.

Access is denied.

  Source=Windows.UI

这是由以下因素触发的：

compositor = new Compositor();

排字员：

private Windows.UI.Composition.Compositor compositor;

这可能是什么原因造成的

在UWP应用程序中，我可以通过分配正确的权限来使用此API，但在示例项目中似乎没有此设置。

应用程序引导未完成。调度器需要按照以下要求设置：
