如何将 Uno 平台与 Windows 社区工具包一起使用

Question

我尝试使用this Uno Platform 模板制作演示应用程序。
我想要做的就是用this example 添加winui2 并用this example 添加Windows 社区工具包。

在做Windows Community Toolkit教程中提到的事情时，就是安装如下Nuget包：

• Uno.Microsoft.Toolkit.Uwp.UI.Controls.DataGrid
  • 适用于 iOS、Android、Web (WebAssembly)
• Microsoft.Toolkit.Uwp.UI.Controls.DataGrid
  • 对于 UWP 应用

并在我的 XAML 中使用以下参考：
xmlns:controls="using:Microsoft.Toolkit.Uwp.UI.Controls"

在 XAML 文件中，我添加了教程提供的以下代码片段：

<controls:DataGrid x:Name="dataGrid">
    <controls:DataGrid.Columns>
        <controls:DataGridTextColumn Header="Rank"/>
        <controls:DataGridComboBoxColumn Header="Mountain"/>
    </controls:DataGrid.Columns>
</controls:DataGrid>

将我带到我的 Shell.xaml 中的以下 XAML 文件：

<ContentControl
    x:Class="AndroidTest.Views.Shell"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:AndroidTest"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    xmlns:prismMvvm="using:Prism.Mvvm"
    xmlns:prismRegions="using:Prism.Regions"

    xmlns:winui="using:Microsoft.UI.Xaml.Controls"
    xmlns:controls="using:Microsoft.Toolkit.Uwp.UI.Controls"

    prismMvvm:ViewModelLocator.AutowireViewModel="True"
    mc:Ignorable="d">


    <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
        <Grid.RowDefinitions>
            <RowDefinition Height="auto"/>
            <RowDefinition Height="*" />
        </Grid.RowDefinitions>
        <StackPanel Grid.Row="0" Margin="20">
            <TextBlock Text="{Binding Title}" FontSize="30" />
            <TextBlock Text="Welcome to Uno/WinUI and Prism!" FontSize="15" />

            <!-- winui -->
            <winui:NumberBox />
            <!-- community toolkit -->
            <controls:DataGrid x:Name="dataGrid">
                <controls:DataGrid.Columns>
                    <controls:DataGridTextColumn Header="Rank"/>
                    <controls:DataGridComboBoxColumn Header="Mountain"/>
                </controls:DataGrid.Columns>
            </controls:DataGrid>

        </StackPanel>
        <ContentControl Grid.Row="1" prismRegions:RegionManager.RegionName="ContentRegion" />
    </Grid>
</ContentControl>

现在代码在 UWP 上运行良好，但不再适用于 Android。我在App.xaml.cs 收到此错误消息：

Prism.Ioc.ContainerResolutionException: 'An unexpected error occurred while resolving 'AndroidTest.Views.Shell''

函数处：

protected override UIElement CreateShell()
{
    return Container.Resolve<Shell>();
}

还有以下输出：

关于我缺少什么的任何想法？

Answer 1

您的问题很可能是链接器问题。你可以看看documentation from Microsoft。

Answer 2

原来是不同版本的 NuGet 包存在问题，以及它们的依赖关系存在问题。
对于具有 Uno 平台、Prism 库和 Windows 社区工具包的功能应用，您需要以下版本：

• Uno 模板Version 3.7.4
• Uno.Microsoft.Toolkit.Uwp.UI.Controls.DataGrid Version 7.0.0.

安装这些 NuGet 包版本时，所有依赖项都是正确的，并且工作正常。
