Después de una investigación de todo el día este comentario Xaml localization: Using .resx Resources in Xaml without x:static he encontrado una solución sencilla para proporcionar soporte multilenguaje con (recursos incrustados o ensamblaje de referencia) * .resx - archivos. Desde Framework 4 hay una clase base llamada DynamicObject para especificar el comportamiento dinámico en tiempo de ejecución en el espacio de nombres System.Dynamic.
que obtendrá según ResourceLoader de System.Dynamic.DynamicObject - clase:
public class ResourceLoader : DynamicObject
{
#region Fields ---------------------------------------------------------------
private const string DefaultResourcesSuffix = "Resource";
private ResourceManager _resourceMan;
private CultureInfo culture;
private readonly string _defaultAssemblyName;
private readonly Assembly _defaultAssembly;
private Assembly theAssembly;
private string resourcesSuffix;
private string assembly;
#endregion // Fields
#region Properties -----------------------------------------------------------
/// <summary>
/// Gets or sets the assembly.
/// </summary>
public string Assembly
{
get { return assembly; }
set
{
assembly = value;
theAssembly = System.Reflection.Assembly.Load(assembly);
_resourceMan = null;
}
}
/// <summary>
/// Gets or sets the resources suffix.
/// </summary>
public string ResourcesSuffix
{
get { return resourcesSuffix; }
set
{
resourcesSuffix = value;
_resourceMan = null;
}
}
/// <summary>

public CultureInfo CurrentCulture
{
get { this.culture = this.culture ?? CultureInfo.InvariantCulture; return this.culture; }
set { this.culture = value; }
}
/// <summary>

private ResourceManager ResourceManager
{
get
{
if (ReferenceEquals(_resourceMan, null))
{
ResourceManager temp = new ResourceManager(
string.Format("{0}.{1}", Assembly ?? _defaultAssemblyName, ResourcesSuffix ?? DefaultResourcesSuffix),
theAssembly ?? _defaultAssembly);
_resourceMan = temp;
}
return _resourceMan;
}
}
#endregion // Properties
#region Methods --------------------------------------------------------------
private object GetResource(string name, CultureInfo language)
{
if (language == null || language == CultureInfo.InvariantCulture)
return ResourceManager.GetObject(name);
return ResourceManager.GetObject(name, language);
}
/// <summary>

/// </summary>
/// <param name="binder">Provides information about the object that called the dynamic operation. The binder.Name property provides the name of the member on which the dynamic operation is performed. For example, for the Console.WriteLine(sampleObject.SampleProperty) statement, where sampleObject is an instance of the class derived from the <see cref="T:System.Dynamic.DynamicObject"/> class, binder.Name returns "SampleProperty". The binder.IgnoreCase property specifies whether the member name is case-sensitive.</param>

/// </returns>
public override bool TryGetMember(GetMemberBinder binder, out object result)
{
result = GetResource(binder.Name, this.culture);
if (result != null && result.GetType() == typeof(System.Drawing.Bitmap))
{
System.Drawing.Bitmap currentBmp = result as System.Drawing.Bitmap;
currentBmp.MakeTransparent(System.Drawing.Color.Magenta);
BitmapSource src = Imaging.CreateBitmapSourceFromHBitmap(currentBmp.GetHbitmap(), IntPtr.Zero, Int32Rect.Empty, BitmapSizeOptions.FromEmptyOptions());
result = src;
}
return result == null ? false : true;

Usted puede crear instancia dentro xaml así:
<Application x:Class="ResourceFileAccessSample.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:src="clr-namespace:ResourceFileAccessSample.ResourceBinding"
StartupUri="Window1.xaml" Startup="Application_Startup" >
<Application.Resources>
<src:ResourceLoader x:Key="resource" CurrentCulture="(Default)" ResourcesSuffix="Resource" />
</Application.Resources>
código C#:
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
private ResourceLoader res;
public Window1()
{
InitializeComponent();
// load it from WPF Resources
this.res = (ResourceLoader)this.FindResource("resource");
// or create an instance
//this.res = new ResourceLoader(CultureInfo.InvariantCulture, "Resource");
this.LayoutRoot.DataContext = res;
}
private void btnSwichLanguage_Click(object sender, RoutedEventArgs e)
{
res.SwitchCulture(new CultureInfo("de"));
this.LayoutRoot.DataContext = null;
this.LayoutRoot.DataContext = res;
}
}
Ahora es posible enlazar las cadenas y las imágenes (las imágenes se convierten en WPF BitmapSource compilant:
<StackPanel Name="LayoutRoot" Orientation="Vertical">
<Label Name="lblText" Content="{Binding Path=rsName, Mode=OneWay}" HorizontalContentAlignment="Center" Margin="5" Padding="0" />
<Image Source="{Binding Path=AlignObjectsTop}" Height="16" Width="16" Margin="5" />
<Button Name="btnSwichLanguage" Content="Switch to de" Click="btnSwichLanguage_Click" MinHeight="25" Width="100" />
</StackPanel>
¿Cómo se creó el archivo de recursos de Mensajes? ¿Acabas de agregar Messages.resx a tu carpeta de propiedades? Si es así, no puedo acceder a este archivo. – Sergey
@Sergey, sin importar dónde se encuentre. Claro que también puedes agregarlo a la carpeta de propiedades. El archivo Sure Resx debe estar en el directorio del proyecto. ¿Puede ser que no puedes agregarlo al directorio de propiedades de VS? Por cierto, es una mala práctica agregar smth al directorio de propiedades. Mejor crea el directorio de "recursos" para mantener tus archivos de res. – 0x49D1
