[IronPython] Hosting IronPython in a Silverlight App

[Michael Foord]

Hello all,

I'm experimenting with hosting IronPython in a silverlight (1.1 alpha 
refresh) app.

When I write C# code that uses the PythonEngine it works fine when 
access *from IronPython code*.

If I use the same code as 'code behind', then it throws an exception 
"The method or operation is not implemented."

(At the line "PythonEngine pe = PythonEngine.CurrentEngine;")

The code is:

using System;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Ink;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using IronPython.Hosting;
using Microsoft.Scripting;

namespace EmbeddedWithCodeBehind
{
    public partial class Page : Canvas
    {
        public void Page_Loaded(object o, EventArgs e)
        {
            // Required to initialize variables
            InitializeComponent();

            try
            {
                PythonEngine pe = PythonEngine.CurrentEngine;
                string code = "lambda x: x.upper()";
                Function<string, string> func = 
pe.EvaluateAs<Function<string, string>>(code);

                string x = "i'm talking loudly";
                string result = func(x);
                textBlock.Text = result;
            }
            catch (Exception ex)
            {
                textBlock.Text = ex.Message;
            }

        }
    }
}



The XAML is:

<Canvas x:Name="parentCanvas"
        xmlns="http://schemas.microsoft.com/client/2007";
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml";
        Loaded="Page_Loaded"
        
x:Class="EmbeddedWithCodeBehind.Page;assembly=ClientBin/EmbeddedWithCodeBehind.dll"
        Width="640"
        Height="480"
        Background="White"
        >

  <TextBlock x:Name="textBlock"></TextBlock>

</Canvas>


Everything else is the default from an Orcas beta 2 new Silverlight project.

Anyone got any clues as to what is happening?

Thanks
