从用户控件导航到页面时出现 TypeLoadException

Question

我的用户控件中有这段代码：

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'.
mscorlib

at Windows.UI.Xaml.Controls.Frame.Navigate(Type sourcePageType)
at Organize.day_btn.clicked(Object sender, TappedRoutedEventArgs e)

我尝试过清理、重建、构建 x64 和 x86，但没有任何帮助。

Answer 1

我首先将 calendar_day 创建为 BlankPage1，然后重命名文件和类。但是在 calendar_day.xaml 我离开了x:Class="Organize.BlankPage1"。
