Optimizing the implementation of INotifyPropertyChanged using [CallerMemberName] in .Net 4.5 and above

Heard about it first time at the BASTA! in Darmstadt, Feb. 2013:
M.Steyer showed new options/freatures of the recent .Net Version. There was also an article in the Windows.developer Magazine by G.Biswanger about it, later. I will pick it up here, too:

The View:

<Window x:Class="WpfApplication1_BindBaseDemo.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:project="clr-namespace:WpfApplication1_BindBaseDemo"
Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
<project:MainWindowViewModel></project:MainWindowViewModel>
</Window.DataContext>
<Grid>
<TextBlock Text="{Binding MyText}"></TextBlock>
</Grid>
</Window>

The ViewModel:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace WpfApplication1_BindBaseDemo
{
  public class MainWindowViewModel : BindBase
  {
    private string myText;
    public string MyText
    {
      get { return myText; }
      set { SetProperty(ref myText,value); }
    }
    public MainWindowViewModel()
    {
      MyText = "Hello World";
    }
  }
}

The Class BindBase.cs using the new [CallerMemberName]:

using System;
using System.Collections.Generic;
using System.ComponentModel; // for INotifyPropertyChanged
using System.Linq;
using System.Runtime.CompilerServices; // for CallerMemberName
using System.Text;
using System.Threading.Tasks;
namespace WpfApplication1_BindBaseDemo
{
  public abstract class BindBase : INotifyPropertyChanged
  {
    public event PropertyChangedEventHandler PropertyChanged;
    protected bool SetProperty<T>(ref T storage, T value, [CallerMemberName]String propertyName = null)
    {
      if (object.Equals(storage, value)) return false;
      storage = value;
      this.OnPropertyChanged(propertyName);
      return true;
    }
    protected void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
      var eventHandler = this.PropertyChanged;
      if (eventHandler != null)
        eventHandler(this, new PropertyChangedEventArgs(propertyName));
    }
  }
}

Schema of a WPF TrayIcon Application

Note: only an overview! (You should add a context menu by clicking on the trayIcon instead showing an BalloonTip and respond on its closing.)

a) create a new wpf application project
b) add an Icon to your Project and let the resource copy to your bin folder
c) add reference to System.Windows.Forms - it Hosts the NotifyIcon!
d) add System.Drawing.Imaging - used to load the *.ico file in the "bin" Folder
e) Name the MainWindows "mainWin" in XAML.
f) add the Events "Closing" and "Closed" to the XAML of the MainWindow!
g) consider the following sample:
