我正在构建我的第一个UWP应用程序，但我遇到了问题。当我在我的计算机上构建并运行我的应用程序 - 为x86构建时 - 它运行得很好。但是当我尝试在我的Windows Phone（ARM）上运行它时，我收到以下错误：
this.RootSplitView.DisplayMode错误CS1061：＆＃39; App＆＃39;不包含 定义＆＃39; RootSplitView＆＃39;没有扩展方法＆＃39; RootSplitView＆＃39; 接受类型＆＃39; App＆＃39;的第一个参数。可以找到（是你 缺少using指令或程序集引用？）

和Xaml：
<Application
x:Class="Conquer_Companion.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Conquer_Companion"
RequestedTheme="Light">
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="ms-appx://Styles/Styles.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
你们可以帮我弄清楚是什么导致了这个吗？
提前致谢！
