Any delegate should work for this so I'd suggest Func<object> instead.

Hi Dino, Thanks for your reply... I had to synchronize threads in order to avoid cross-threading operations. I have Ironpython hosted on an aplication with plugins, every time I accessed some form control ( Plugin Form Designer ) I got a cross-thread error, so I needed to invoke that instance. CallTarget solved my problem... Do you know any other methodology that works better then CallTarget? Thank you, António Piteira 2009/2/22 Dino Viehland <di...@microsoft.com<mailto:di...@microsoft.com>> Depending on what you're doing you might be better off using Func<object> instead of CallTarget0. CallTarget0 is more of a Python implementation detail and could change w/ major IronPython versions - or even be replaced w/ Func<object>. it's primary purpose is to be the delegate for calling a zero-arg Python function so it could change due to changes in how we implement functions. Func<object> will always exist and do exactly what it says. Of course if you are actually doing something w/ calling classes or functions then it's the right thing to use.

Found the solution... clr.AddReference("Ironpython") from IronPython.Compiler import CallTarget0 I was looking in the wrong place. -------------------------------------------------------------------------------------------------------------------------- I've been searching for CallTarget0 and from what I read it should be in Microsoft.Scripting.dll, but when I add the reference to clr and import CallTarget0 from Microsoft.Scripting.dll I get this message: --------------------------- Error... --------------------------- Cannot import name CallTarget0 --------------------------- OK --------------------------- Any ideas?
