Question

在我的Windows Phone 8.1应用程序中，我创建了一个CustomPage，然后导航到它，所有代码都在后面。我的CustomPage类是：

using Windows.UI.Xaml.Controls;

namespace TestApp {
    public class CustomPage : Page {
        public CustomPage() {
            this.BuildPage();
        }

        private void BuildPage() {
            var panel = new StackPanel();
            panel.Children.Add(new TextBlock { Text = "Hello World" });
            this.Content = panel;
        }
    }
}

然后在我的MainPage.xaml.cs我这样做：

CustomPage myNewPage = new CustomPage();
Frame.Navigate(myNewPage.GetType());

但是这会引发System.TypeLoadException异常 - Could not find Windows Runtime type 'Windows.Foundation' 如果我不做一个CustomPage类只是一个Page类，它工作正常，但我需要创建一个CustomPage类，我怎么能解决这个问题？

更新的
这是堆栈跟踪

MyCustomClass.DLL!HelpingTool.NavigateToNewPage() Line 50   C#
MyCustomClass.DLL!HelpingTool.InitializeToolset() Line 23   C#
MyCustomClass.DLL!HelpingTool.HelpingTool(Windows.UI.Xaml.Controls.Page mainPage = {TestApp.MainPage}) Line 18  C#
TestApp.exe!TestApp.MainPage.Button_Click(object sender = {Windows.UI.Xaml.Controls.Button}, Windows.UI.Xaml.RoutedEventArgs e = {Windows.UI.Xaml.RoutedEventArgs}) Line 88 C#

和我的MainPage.xaml的内容

<Page
    x:Class="TestApp.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    mc:Ignorable="d"
    Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">

    <Grid x:Name="LayoutRoot">
        <Grid.RowDefinitions>
            <RowDefinition Height="2*" />
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <Grid x:Name="myGrid" Grid.Row="0">
            <TextBlock x:Name="OutputText">
                    Output will appear here <LineBreak />
            </TextBlock>
        </Grid>

        <ScrollViewer Grid.Row="1" VerticalAlignment="Stretch">
            <Button Content="Do something" Click="Button_Click" HorizontalAlignment="Center" />
        </ScrollViewer>
    </Grid>
</Page>

System.TypeLoadException无法找到Windows运行时类型“Windows.Foundation”异常
