将富文本文档作为嵌入资源加载时 UWP 挂起

Question

我正在尝试在我的应用中包含一些富文本，但在尝试加载文本时应用挂起。

// Here is the initiating call:
await aboutDialog.ShowAsync();

// This code hangs on the second line
private async void Page_Loaded(object sender, RoutedEventArgs e)
{
    var stream = Assembly.GetExecutingAssembly().GetManifestResourceStream("XamlSandbox.cities.rtf");
    myRichEditBox.Document.LoadFromStream(Windows.UI.Text.TextSetOptions.FormatRtf, stream.AsRandomAccessStream());
}

// This code works OK
private async void Page_Loaded(object sender, RoutedEventArgs e)
{
    var picker = new Windows.Storage.Pickers.FileOpenPicker();
    var file = await picker.PickSingleFileAsync();
    var fileStream = await file.OpenAsync(FileAccessMode.Read);
    myRichEditBox.Document.LoadFromStream(Windows.UI.Text.TextSetOptions.FormatRtf, fileStream);
}

我尝试将嵌入式资源加载到内存流中并使用它，但这也挂起。有什么想法吗？

这是在 UWP 中正确加载嵌入资源的方法：

            var rtfUri = new Uri("ms-appx:///cities.rtf");
            var file = await StorageFile.GetFileFromApplicationUriAsync(rtfUri);
            var stream = file.OpenAsync(FileAccessMode.Read);
            myRichEditBox.Document.LoadFromStream(Windows.UI.Text.TextSetOptions.FormatRtf, stream.GetResults());
