Works for me:


Python 2.5.4 (r254:67916, Dec 23 2008, 15:10:54) [MSC v.1310 32 bit (Intel)]
Type "copyright", "credits" or "license" for more information.

IPython 0.10 -- An enhanced Interactive Python.
?         -> Introduction and overview of IPython's features.
%quickref -> Quick reference.
help      -> Python's own help system.
object?   -> Details about 'object'. ?object also works, ?? prints more.

In [5]: clr.AddReference('FactoryPattern')

...but I was in the same directory as the dll. Are you in the same directory?
What happens if you try to put the full path? e.g.

clr.AddReference(r'C:\temp\PythonDotNET\FactoryPattern')

If that doesn't work does using Assembly.LoadFile work? e.g.

from clr import System
from System import Reflection
full_filename = r'C:\temp\PythonDotNET\FactoryPattern.dll'
Reflection.Assembly.LoadFile(full_filename)

HTH,
