InitializeComponent() 无法根据系统语言定位资源

Question

该应用程序是在运行 windows10 机器上开发的，系统语言设置为我们当地的语言，丹麦语。现在我们正处于需要在其他国家的办公室使用该软件的阶段。但是，视图在这些机器上启动时崩溃，而且我发现如果我在自己的机器上更改系统语言，它也不会为我工作。这是为什么，我们搞不清楚。

来自 InitializeComponent 的错误消息：

System.IO.IOException: 'Cannot locate resource 'views/main/mainview.xaml'.'

堆栈跟踪：

下面是部分代码：

App.xaml

<!--ANCHOR: Updater-->
<updater:SingleInstanceApplication x:Class="InfoCenter.App"
                                   x:Name="App"
                                   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                                   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                                   xmlns:updater="clr-namespace:InfoCenter.Updater">
    <Application.Resources>
    </Application.Resources>
</updater:SingleInstanceApplication>

App.xaml.cs:

protected override void OnStartup(StartupEventArgs e)
{
    if (PreProcessor.Prod)
        Dispatcher.UnhandledException += OnDispatcherUnhandledException;

    base.OnStartup(e);

    AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);

    var app = new MainView { ShowInTaskbar = false, Topmost = true }
    var context = new MainViewModel();
    app.DataContext = context;
    app.Show();
}

其他信息： - 我们使用 ClickOnce 进行部署。 - 该应用程序有一些后台任务将保持运行。看起来它只是在没有视图的情况下运行。 - 我们使用 MVVM 模式。

如果我遗漏了一些信息，请随时询问！

这是关于文化信息的问题，因为您已经在资源文件中添加了这一行

<UICulture>en-US</UICulture>

按照 this post 你应该能够解决你的问题取消注释这一行

[assembly: NeutralResourcesLanguage("en-US", UltimateResourceFallbackLocation.Satellite)]

在你的assembly.info.cs
