I am trying to get asynchronous delegates to work in 1.1.2 and 2.0 beta3, both fail for me, here is what I am trying to do
from IronPython.Runtime.Calls import CallTarget0 def printHi(): print 'hi' delegate = CallTarget0(printHi) async_result = delegate.BeginInvoke(None, None) delegate.EndInvoke(async_result) Here is what I get: Traceback (most recent call last): File , line 0, in <stdin>##22 File , line 0, in EndInvoke##23 SystemError: Object reference not set to an instance of an object.
