The warning is overly aggressive in this case - the warning is removed for the next release and your code will still work so you can ignore it.

Subject: [IronPython] Deprecation warning on Windows Form Double Buffered

Hi All,

With the following code I am getting a warning:

DeprecationWarning: Accessing protected method DoubleBuffered from non-derived type Form

import clr
from System import *
from System.Windows.Forms import *
class LDForm(Form):

    def __init__(self):
        self.DoubleBuffered = True
    def __call__(self):


Is this related to the import changes? I've not been doing much Pythoning lately so sorry if I have missed something...
