How to integrate WPF NotifyIcon using Caliburn.Micro

I was wondering how to integrate NotifyIcon using Caliburn.Micro.

I am trying to integrate with Caliburn using the low-level Caliburn API. Here are the classes:

ITrayIconManager

public interface ITrayIconManager
{
    ITrayIcon GetOrCreateFor<T>();
}

ITrayIcon (wrapper around TaskbarIcon from WPF NotifyIcon)

 public interface ITrayIcon : IDisposable
{
    void ShowBalloonTip(string title, string message, BalloonIcon symbol);
    void Show();
    void Hide();
}

ISetTrayIconInstance

public interface ISetTrayIconInstance
{
    ITrayIcon Icon { set; }
}

TrayIconwrapper

public class TrayIconWrapper : ITrayIcon
{
    private readonly TaskbarIcon icon;

    public TrayIconWrapper(TaskbarIcon icon)
    {
        this.icon = icon;
    }

    public bool IsDisposed { get; private set; }

    public void Dispose()
    {
        icon.Dispose();
        IsDisposed = true;
    }

    public void Show()
    {
        icon.Visibility = Visibility.Visible;
    }

    public void Hide()
    {
        icon.Visibility = Visibility.Collapsed;
    }

    public void ShowBalloonTip(string title, string message, BalloonIcon symbol)
    {
        icon.ShowBalloonTip(title, message, symbol);
    }
}

TrayIconmanager

public class TrayIconManager : ITrayIconManager
{
    private readonly IDictionary<WeakReference, WeakReference> icons;

    public TrayIconManager()
    {
        icons = new Dictionary<WeakReference, WeakReference>();
    }

    public ITrayIcon GetOrCreateFor<T>()
    {
        if (!icons.Any(i => i.Key.IsAlive && typeof(T).IsAssignableFrom(i.Key.Target.GetType())))
            return Create<T>();

        var reference = icons.First(i => i.Key.IsAlive && typeof(T).IsAssignableFrom(i.Key.Target.GetType())).Value;
        if (!reference.IsAlive)
            return Create<T>();

        var wrapper = (TrayIconWrapper)reference.Target;
        if (wrapper.IsDisposed)
            return Create<T>();

        return wrapper;
    }

    private ITrayIcon Create<T>()
    {
        var rootModel = IoC.Get<T>();
        var view = ViewLocator.LocateForModel(rootModel, null, null);
        var icon = view is TaskbarIcon ? (TaskbarIcon)view : new TaskbarIcon();
        var wrapper = new TrayIconWrapper(icon);

        ViewModelBinder.Bind(rootModel, view, null);
        SetIconInstance(rootModel, wrapper);
        icons.Add(new WeakReference(rootModel), new WeakReference(wrapper));

        return wrapper;
    }

    private void SetIconInstance(object rootModel, ITrayIcon icon)
    {
        var instance = rootModel as ISetTrayIconInstance;
        if (instance != null)
            instance.Icon = icon;
    }
}

This is the code, now how to use it? This code is based on Caliburn View - ViewModel binding, i.e. I need to create a ViewModel for TasbarkIcon and View (which should be inherited from the TaskbarIcon element ):

TrayIconViewModel

public class TrayIconViewModel : IMainTrayIcon, ISetTrayIconInstance
{
    public TrayIconViewModel()
    {

    }

    public ITrayIcon Icon { get; set; }

    public void ShowWindow()
    {
        Icon.Hide();
        System.Windows.Application.Current.MainWindow.Show(); //very very bad :(
    }

ITrayIcon is a shell for managing TaskbarIcon. Now I can call methods on it from my ViewModel, which is great.

TrayIconView (cal: Message: Attach - ShowWindow )
