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

Question

我在使用 Windows 10 UWP 应用商店应用时遇到问题。

应用程序中有两个页面（Page1 和 Page2）具有类似的 xaml 控件，但一个页面（Page1）在 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，Page1 的初始化会引发异常。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可以完美运行。在我的本地机器上，我没有异常，没有警告，Windows 认证工具包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在测试人的电脑上没有异常。

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>

Page2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>

也许有人有想法。谢谢！

Answer 1

我已经测试了 page1 和 page2 的 XAML 代码，它对我来说工作正常。

你能给我提供第 1 页的代码吗？

您用于此项目的 sdk 版本。

谢谢。
