Hello Python Community,
We're quite pleased to announce the release of "IronPython 2.6 CTP for .NET 4.0
Beta 1". This is our second preview of IronPython running under the Dynamic
Language Runtime that is built directly into a .NET 4.0 release! As before,
this release allows you to use IronPython objects and types as .NET 4.0 dynamic
objects from within C# and Visual Basic code. While this release does share a
bit in common with the upcoming IronPython 2.6 Beta 1 release (e.g., a number
of MSI improvements), the core functionality is essentially that of IronPython
2.6 Alpha 1. Please also note that "IronPython 2.6 CTP for .NET 4.0 Beta 1"
will run only under .NET 4.0 Beta 1.
Here's a small example showing just how powerful the new dynamic feature is for
taking advantage of dynamic language functionality in statically typed
languages:
<mock.py>
import random, math
class Mock(object):
def __getattr__(self, key):
"""Mock objects of this type will dynamically implement any
requested member"""
return random.choice(["hello world", math.pi])
</mock.py>
<dynamic_demo.cs>
using System;
using IronPython.Hosting;
using Microsoft.Scripting.Hosting;
public class dynamic_demo {
static void Main() {
var ipy = Python.CreateRuntime();
dynamic mock = ipy.UseFile("mock.py");
dynamic m = mock.Mock();
//The Python Mock type dynamically implements any member that is
requested of it
System.Console.WriteLine(m.the_csharp_compiler_cannot_possbily_know_this_member_exists_at_compile_time);
}
}
<dynamic_demo.cs>
To try out this preview release:
1. Install some variant of .NET 4.0 Beta 1 or Visual Studio 2010 Beta 1.
E.g.,

2. Install IronPython.msi from
http://ironpython.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=27320
3. Follow any of the many dynamic walkthroughs online.

would be a good start
Have fun!
