Right variant for .NET 4.5 +

C# code

public class VersionManager
{
    private static string filterString;

    public static string FilterString
    {
        get => filterString;
        set
        {
            if (filterString == value)
                return;

            filterString = value;

            StaticPropertyChanged?.Invoke(null, FilterStringPropertyEventArgs);
        }
    }

    private static readonly PropertyChangedEventArgs FilterStringPropertyEventArgs = new PropertyChangedEventArgs (nameof(FilterString));
    public static event PropertyChangedEventHandler StaticPropertyChanged;
}

XAML binding (attention to braces they are (), not {})
