我正在尝试覆盖Windows Phone Control Toolkit ContextMenu控件的默认模板。当我从Toolkit source code中的Generix.xaml复制并粘贴样式（无需修改）并运行时，长按我得到

  

ArgumentException：值不在预期范围内。

如果我将其删除，那么它可以正常工作。覆盖MenuItem和Separator控件的模板也可以顺利运行。

这是Toolkit中定义的默认样式：

我也尝试删除各个部分，例如VisualStateGroups，但没有运气。

修改 例外是ApplicationUnhandledExceptionEventArgs事件中的Application_UnhandledException对象。该对象不提供其他信息。
