Question

尝试导航到Windows Phone 8.1应用程序中的页面时，我遇到了一个非常奇怪的异常（通用）

A first chance exception of type 'Windows.UI.Xaml.Markup.XamlParseException' occurred in MyApplcation.exe
WinRT information: Cannot create instance of type '%0' [Line: 25 Position: 44]

它还说：

The text associated with this error code could not be found.

我的MainPage.xaml.cs中有一些代码导航到一个名为details的页面：

 private void Button_Click(object sender, RoutedEventArgs e)
        {
            Frame.Navigate(typeof(Details));
        }

详细信息代码非常少：

<Page
    x:Class="MyApplcation.Views.Details"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:MyApplcationViews"

    xmlns:mmppf="using:Microsoft.PlayerFramework"
    mc:Ignorable="d"
    Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Page.Resources>

    </Page.Resources>
    <Grid>
        <Rectangle Fill="#FF152853" HorizontalAlignment="Left" Height="260" VerticalAlignment="Top" Width="491" Name="videoBack"/>

        <Image x:Name="preview_image" HorizontalAlignment="Left" Height="260" Margin="0,10,0,0" VerticalAlignment="Top" Width="56" Stretch="UniformToFill"/>
        <Border x:Name="layoverBorder" CornerRadius="50" BorderBrush="Transparent" BorderThickness="2" Margin="196,63,196,689" Background="#FFFEFEFE" Opacity="1"  >
            <Image x:Name="layoverImage" HorizontalAlignment="Left" Height="51.671" Margin="20,14.674,0,0" VerticalAlignment="Top" Width="56.372" Source="ms-appx:///Assets/triangle-64 (2).png" Stretch="None" RenderTransformOrigin="0.5,0.5" UseLayoutRounding="False" d:LayoutRounding="Auto">
                <Image.RenderTransform>
                    <CompositeTransform Rotation="90.899"/>
                </Image.RenderTransform>
            </Image>
        </Border>
        <mmppf:MediaPlayer x:Name="player" Source="{Binding Video}" Margin="0,0,0,587"/>
    </Grid>
</Page>

当我删除<mmppf:MediaPlayer...行时，页面导航正常工作。

我不知道从哪里开始，因为抛出的异常是如此模糊。

使用Windows Phone 8.1 mmppf时出错 - 尝试导航到页面时出现解析异常
