Vb.net 从usercontrol导航到页面时出现TypeLoadException

我的Usercontrol中有以下代码：

Private Sub tap(sender As Object, e As TappedRoutedEventArgs) Handles Me.Tapped
     Try
        CType(Window.Current.Content, Frame).Navigate(GetType(calendar_day))
        'calendar_day is a page in project'
    Catch ex As Exception
        Debug.WriteLine(ex.HelpLink)
        Debug.WriteLine(ex.HResult)
        Debug.WriteLine(ex.InnerException)
        Debug.WriteLine(ex.Message)
        Debug.WriteLine(ex.Source)
        Debug.WriteLine(ex.StackTrace)
    End Try
End Sub

输出：

A first chance exception of type 'System.TypeLoadException' occurred in Organize.exe

Could not find Windows Runtime type 'Windows.Foundation'.

我尝试过清理、重建和构建x64和x86，但没有任何帮助。

我首先将日历日创建为BlankPage1，然后重命名了文件和类。但是在calendar_day.xaml中，我离开了

x:Class=“Organize.BlankPage1”

谢谢你的提示。我有一个类似的错误，原因是Page类应该位于Views命名空间中。
