I think it might be just "Dynamic" in 2.0. From: [email protected] [mailto:[email protected]] On Behalf Of Curt Hagenlocher Sent: Tuesday, April 14, 2009 11:05 AM To: Discussion of IronPython Subject: Re: [IronPython] **kwargs and __getattr__ handling in csharp functions and classes?
It should be Microsoft.Scripting.DynamicObject in 2.0. On Tue, Apr 14, 2009 at 11:02 AM, Alex News <[email protected]<mailto:[email protected]>> wrote: Current IronPython = 2.01? I have Microsoft.Scripting.Core referenced, and can't find DynamicObject. There is an Microsoft.Scripting.Actions.IDynamicObject, and a Microsoft.Scripting.Runtime.IOldDynamicObject. I'm sure I'm missing something very basic.
