WPF l10n with bindings

using System.ComponentModel;
using System.Globalization;
using System.Resources;
using System.Windows.Data;

public class TranslationSource
        : INotifyPropertyChanged
{
    private static readonly TranslationSource instance = new TranslationSource();

    public static TranslationSource Instance
    {
        get { return instance; }
    }

    private readonly ResourceManager resManager = Properties.Resources.ResourceManager;
    private CultureInfo currentCulture = null;

    public string this[string key]
    {
        get { return this.resManager.GetString(key, this.currentCulture); }
    }

    public CultureInfo CurrentCulture
    {
        get { return this.currentCulture; }
        set
        {
            if (this.currentCulture != value)
            {
                this.currentCulture = value;
                var @event = this.PropertyChanged;
                if (@event != null)
                {
                    @event.Invoke(this, new PropertyChangedEventArgs(string.Empty));
                }
            }
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
}

public class LocExtension
    : Binding
{
    public LocExtension(string name)
        : base("[" + name + "]")
    {
        this.Mode = BindingMode.OneWay;
        this.Source = TranslationSource.Instance;
    }
}

Since I had a bit of trouble figuring out how to actually use the class, heres examples to help others:

XAML:
xmlns:local="clr-namespace:MyNamespace.LocalizationNamespace"
The namespace for xaml is whatever you set it in the class.

Usage:
"{local:Loc <PropertyName>}"

C#:
Properties.Resources.ResourceManager.GetString(nameof(Properties.Resources.<PROPERTYNAME>), Localization.TranslationSource.Instance.CurrentCulture);

And for switching to the actual culture:
C#:
Localization.TranslationSource.Instance.CurrentCulture = CultureInfo.GetCultureInfo("en-example");

@nevaran - you can check the blog post that I wrote about this. It explains how it works a little bit better (although it might not be fully explanatory).

I *just* figure it out, but thanks anyway; going to update the comment to help others

@jakubfijalkowski, thanks for your code. Is there a way to allow something like this?
{ns:Loc {Binding ViewModelProperty}}

@lszczygielek If my memory is not mistaken, that is possible with some changes to the code (i.e. you need to handle the binding somewhat yourself). Unfortunately, I haven't touched it in years and won't be able to help what needs to be changed.

How come, no one ever posts the actual source code?
I realize that some people are able to read the class, and implement it. But some still require assistance, as clearly demonstrated in every comment section, on this topic.

Years ago I desperately needed this feature and as a result I implemented the most complete version of it in the legendary HandyControls.
