IronPython - SIlverLight

Here is the adapted version of ScottGu sample

from System.Windows import Application
from System.Windows.Controls import UserControl

class App:

  root = None

  def MyButton_Click(self,s,e):
    App.root.MyButton.Content = "Pushed"
    App.root.Message.Text = "MyButton has been pushed"

  def __init__(self):
    App.root = Application.Current.LoadRootVisual(UserControl(), "app.xaml")
    App.root.Message.Text = "Welcome to Python and Silverlight!"
    App.root.MyButton.Content = "Push Me"
    App.root.MyButton.Click += self.MyButton_Click
  
App()
