We’ve made change recently (last week) on .NET 2.0 you’ll need to use a different namespace and assembly:
import clr clr.AddReference(‘Microsoft.Scripting’) from Microsoft.Scripting.Utils import Func Func[object, object](targetCallableHere) Tomas From: [email protected] [mailto:[email protected]] On Behalf Of Michael Foord Sent: Monday, September 14, 2009 11:04 AM To: Discussion of IronPython Cc: Discussion of IronPython Subject: Re: [IronPython] CallTargetX delegates -- http://www.ironpythoninaction.com On 14 Sep 2009, at 18:59, Dino Viehland <[email protected]<mailto:[email protected]>> wrote: To use Func you just need to do: import clr clr.AddReference(‘System.Core’) from System import Func Func[object, object](targetCallableHere) This is equivalent to CallTarget1. You can add more “object, “ or you can replace object with some other type. It is of course dependent on .NET 3.

For example, how would you change the Invoke calls in onChanged and onRenamed here: http://www.ironpython.info/index.php/Invoking_onto_the_GUI_%28Control%29_Thread I've never seen how to use Func within an IP script, just within C#.

Sounds like it could be a common 'gotcha' especially for newbies running old example code.
