C# 我之所以能'；不能同时移动或调整我的小部件Xbox游戏栏？

这（1）是Package.appxmanifest的开始

<Package xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10"

                         Id="Widget"
                         DisplayName="llllllllll"
                         Description="llllllllll"
                         PublicFolder="GameBar">
        <uap3:Properties>
          <GameBarWidget Type="Standard">
            <HomeMenuVisible>true</HomeMenuVisible>
            <PinningSupported>true</PinningSupported>
            <Size>
              <Height>450</Height>
              <Width>250</Width>
            </Size>
            <ResizeSupported>

              <Vertical>true</Vertical>
            </ResizeSupported>
          </GameBarWidget>
        </uap3:Properties>
      </uap3:AppExtension>
    </uap3:Extension>
  </Extensions>

这些行是红色的（无法理解），我的小部件XGB无法调整大小或移动，尽管我的清单中有这（2）

<Application Id="App"
  Executable="$targetnametoken$.exe"

    <uap3:Extension Category="windows.appExtension">
      <uap3:AppExtension Name="microsoft.gameBarUIExtension"
                         Id="Widget"
                         DisplayName="llllllllll"
                         Description="llllllllll"
                         PublicFolder="GameBar">
        <uap3:Properties>
          <GameBarWidget Type="Standard">
            <HomeMenuVisible>true</HomeMenuVisible>
            <PinningSupported>true</PinningSupported>

              <Height>450</Height>

          </GameBarWidget>
