<p class=MsoNormal>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.<o:p></o:p></p>

<p class=MsoNormal>CallTarget solved my problem... Do you know any other
methodology that works better then CallTarget?<o:p></o:p></p>

<p><span style='font-size:11.0pt;color:#1F497D'>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.</span><o:p></o:p></p>

I've been searching for <u><span style='color:#0000EE'>CallTarget0</span></u><span
style='color:#0000EE'> </span>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:<o:p></o:p></p>
