wpf - XML 命名空间“using:Microsoft.UI.Xaml.Controls”中不存在标记“XamlControlsResources”

Question

我试图使用 WinUI，所以我从 Nuget 安装了插件 Microsoft.UI.Xaml (2.4.2) 并按照说明添加 This <XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls"/>to my App.Xaml

这是我的 App.Xaml 文件

<Application x:Class="WpfApp1.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:WpfApp1"
    StartupUri="MainWindow.xaml">
        <Application.Resources>
            <XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls" />
        </Application.Resources>
</Application>

但它说：

XML 命名空间“using:Microsoft.UI.Xaml.Controls”中不存在标记“XamlControlsResources”

我尝试了 WinUI 插件的旧版本并尝试了 .Net Core 和 Framework，但仍然遇到此问题

Answer 1

I believe this WinUI 2.4.2 library is only compatible if you create a UWP application, not a WPF app.

Having said that, according to this documentation from Microsoft, starting with WinUI 3, you will be able to do this in WPF.

Answer 2

添加

<package id="Microsoft.UI.Xaml" version="2.5.0-prerelease.200812001" targetFramework="native" />

如果您浏览并找不到它，请将包含上述内容的行添加到 packages.config 文件检查安装并等待还原显示在 Nuget 工具中。

确保参考在<Import Project="packages\Microsoft.UI.Xaml" version="2.5.0-prerelease.200812001..."

以及<Error Condition="!Exists('packages\Microsoft.UI.Xaml" version="2.5.0-prerelease.200812001..." 您项目的 .vcxproj 文件中的内容。
