Windows 10 UWP XAML stowed_exception_802b000a_my_app.dll！windows :: ui :: xaml :: iapplicationstatics__impl :: stubclass.loadcomponent

我有一个Windows 10 UWP商店应用程序的问题 .

在应用程序中有两个页面（Page1和Page2）具有类似的xaml控件，但是一个页面（Page1）在通过microsoft测试应用程序时会导致很多问题 . 如果他们尝试启动应用程序，则Page1的初始化会抛出异常 . 当我删除一个特定的xaml控件时，一切都很好，但是Page2包含完全相同的控件并且工作正常 . 在我的本地机器上我没有例外，没有警告，Windows认证套件说应用程序没有问题，我无法重现异常 .

当我从Page1上的CommandBar中删除AppBarButtons时，测试Microsoft测试人员也不例外 . Page2上类似的CommandBar在测试人员的计算机上没有异常 .

Page1的Xaml代码（有问题）：

<Page
    x:Class="MyApp.Page1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:MyApp"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Page.BottomAppBar>
        <CommandBar x:Name="cbCommandBar">

            <AppBarButton x:Name="pageBack" Label="Zurück" HorizontalAlignment="Center" VerticalAlignment="Top" Click="pageBack_Click">
                <AppBarButton.Icon>
                    <SymbolIcon Symbol="Previous"/>
                </AppBarButton.Icon>
            </AppBarButton>

            <AppBarButton x:Name="pageNext" Label="Vor" HorizontalAlignment="Center" VerticalAlignment="Top" Click="pageNext_Click">
                <AppBarButton.Icon>
                    <SymbolIcon Symbol="Next"/>
                </AppBarButton.Icon>
            </AppBarButton>

            <CommandBar.SecondaryCommands>
                <AppBarButton x:Name="firstPage" Label="Erste Seite" Click="firstPage_Click"/>
            </CommandBar.SecondaryCommands>
        </CommandBar>
    </Page.BottomAppBar>
</Page>

第2页的Xaml代码：

<Page
    x:Class="MyApp.Page2"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:MyApp"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d">

    <Page.BottomAppBar>
        <CommandBar x:Name="cbCommandBar">

            <AppBarButton x:Name="downloadImage" Content="Herunterladen" Label="Herunterladen" HorizontalAlignment="Right" VerticalAlignment="Top" Click="downloadImage_Click">
                <AppBarButton.Icon>
                    <SymbolIcon Symbol="Download"/>
                </AppBarButton.Icon>
            </AppBarButton>

            <CommandBar.SecondaryCommands>
                <AppBarButton x:Name="viewInBrowser" Label="Webansicht" Click="viewInBrowser_Click"/>
            </CommandBar.SecondaryCommands>
        </CommandBar>
    </Page.BottomAppBar>
</Page>
