[IronPython] clr.AddRefernce* woes

[Shawn Wheatley]

Hi All!

I just got back from PyCon, where I got to see Martin Maly's talk on
IronPython. I see that Beta 3 is causing quite a bit of problems. I
seem to be having more problems than most, but that may be due to how
I set up my environment. Could someone help me?

Here's what I did:
1) Downloaded the latest IP beta and unpacked to C:\Program
Files\IronPython-1-Beta3
2) Added C:\Program Files\IronPython-1-Beta3 to my path
3) Created a batch file to launch IronPythonConsole:
"C:\Program Files\IronPython-1-Beta3\IronPythonConsole" %1 %2 %3 %4 %5
%6 %7 %8 %9
4) When trying to do any import that involves a reference, I get an error:

C:\Program Files\IronPython-1-Beta3>ipc
IronPython 1.0.2237 (Beta) on .NET 2.0.50727.42
Copyright (c) Microsoft Corporation. All rights reserved.
>>> import clr
>>> import System
>>> clr.AddReference(System.Reflection.Assembly.Load('System.Xml'))
Traceback (most recent call last):
  File , line 0, in input##76
IOError: Could not load file or assembly 'System.Xml' or one of its dependencies
. The system cannot find the file specified.
>>> clr.AddReference(System.Reflection.Assembly.LoadFrom('System.Xml'))
Traceback (most recent call last):
  File , line 0, in input##94
IOError: Could not load file or assembly 'file:///C:\Program Files\IronPython-1-
Beta3\System.Xml' or one of its dependencies. The system cannot find the file sp
ecified.
>>> clr.AddReference(System.Reflection.Assembly.LoadWithPartialName('System.Xml'
))

Process is terminated due to StackOverflowException.

C:\Program Files\IronPython-1-Beta3>

If anybody could help me out I'd really appreciate it.

Thanks,
Shawn Wheatley
