[IronPython] IronPython and serializing object and a few questions

[Mikołaj Dawidowski]

Hello all,
 
.NET and IronPython +WPF is a great combination. Looking forward to use its
final version
I started educating myself on those 3 and have some questions:
 
1. How to serialize IronPython objects? I have some apps written in "normal"
Python and use gnosis.xml.pickle to save and load data.
I tried to load pickle, gnosis.xml.pickle from IronPythonConsole but this is
what I got.
 
IronPython 0.9.3 on .NET 2.0.50215.322

>>> import sys
>>> sys.path.append("c:/python24/lib")
>>> sys.path.append("c:/python24/libs")
>>> import gnosis.xml.pickle
Traceback (most recent call last):
   at <shell>
ImportError: No module named gnosis.xml.pickle
>>> import pickle
Traceback (most recent call last):
   at <shell>
   at pickle.Initialize() in c:\python24\lib\pickle.py:line 32
ImportError: No module named marshal
>>> import cPickle
Traceback (most recent call last):
   at <shell>
ImportError: No module named cPickle

I saw the tutorial in 0.9.5 distro - but
sys.LoadAssemblyByName("System.Xml") doesn't do exactly what pickle does,
does it?
 
2. I have .NET with WinFX from September 2005 CTP and IronPython 0.9.3 works
but 0.9.5 requries newer .NET.
 .NET version and WinFX September 2005 CTP 
IronPython 0.9.3 on .NET 2.0.50215.322

>>> import sys
>>>
 
This is what 0.9.5 whine: "0.9.5 To run this application, you first must
install one of the following versions of the .NET Framework: v2.0.50727"
 
So i guess this is telling me to update my .NET wright? :) Ok, my question
is not so pythonic but I think you guys have experience.
Do I have to uninstall whole WinFX SDK and after installing new .NET install
it again? And  the most important:
Will WinFX still working with that new .NET ?
 
3. IronPython generates exec's from scripts. But when executed they crash.
Should they work? Maybe the should be ran differently...
 
Best regards and GREAT WORK!!
