Multilanguage wpf application with resources in Visual Studio Designer

This is my issue: I have multilanguage WPF application with resources in two different files. Now I choose the proper one in app.xaml.cs like this:

var dict = new ResourceDictionary();
switch (Thread.CurrentThread.CurrentCulture.ToString())
{
    case "de-DE":
        dict.Source = new Uri("pack://application:,,,/Resources;component/StringResources.de-DE.xaml", UriKind.Absolute);
        break;
    default:
        dict.Source = new Uri("pack://application:,,,/Resources;component/StringResources.xaml", UriKind.Absolute);
        break;
}
Resources.MergedDictionaries.Add(dict);

and everything works fine, but I can't see that resources in VisualStudio Designer.

On the other hand when I define ResourceDictionary in App.xaml file like this:

<Application x:Class="Ampe.UI.Views.App"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Exit="App_OnExit" ShutdownMode="OnMainWindowClose">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/Resources;component/StringResources.de-DE.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

then I have this resources in designer but I can't set multilanguage.

Is there any possibility to visible resources in designer with multilanguage application? Maybe some kind of change app.xaml file while application is turn on?

You are on the right way.

  1. I'd recommend you to clear application merged dictionaries before adding new ones. 

        Resources.MergedDictionaries.Clear();
    var dict = new ResourceDictionary();
    switch (Thread.CurrentThread.CurrentCulture.ToString())
    {
        case "de-DE":
            dict.Source = new Uri("pack://application:,,,/Resources;component/StringResources.de-DE.xaml", UriKind.Absolute);
            break;
        default:
            dict.Source = new Uri("pack://application:,,,/Resources;component/StringResources.xaml", UriKind.Absolute);
            break;
    }
    Resources.MergedDictionaries.Add(dict);

  2. Your app.xaml should look like you said:

    <Application x:Class="Ampe.UI.Views.App"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Exit="App_OnExit" ShutdownMode="OnMainWindowClose">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/Resources;component/StringResources.de-DE.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

  3. When you get localized values from resources, you have to use DynamicResources instead of StaticResources:

    <TextBlock Text="{DynamicResource MyString}" />

It works for me. Hope it helps.
