Cool - for some reason this didn't work for me the first time I tried it 
(I must have done something wrong). My minimal IronPython/Silverlight 
example is now a single Python file (app.py) containing:

from System.Windows import Application
from System.Windows.Controls import Canvas, TextBlock

canvas = Canvas()
textblock = TextBlock()
textblock.FontSize = 24
textblock.Text = 'Hello world from IronPython'
canvas.Children.Add(textblock)

Application.Current.RootVisual = canvas

Me too. :-)
