Func/Action delegates are in System.Core assembly and System namespace in CLR4.
So you need to import them conditionally based on current .NET version.

If you use IronPython on .NET 3.5 you'll get 2 different Func/Action delegate 
sets - one in [Microsoft.Scripting]Microsoft.Scripting.Utils and the other in 
[System.Core]System.
It shouldn't matter much which ones do you use. 

  


So if you want to support running on .NET 2, 3 & 4 it's a bit of a mess. 
:-) Sure glad CallTarget0 is sticking around...

Re: [IronPython] CallTargetX delegates

Func/Action delegates are in System.Core assembly and System namespace in CLR4.
So you need to import them conditionally based on current .NET version.

If you use IronPython on .NET 3.5 you'll get 2 different Func/Action delegate 
sets - one in [Microsoft.Scripting]Microsoft.Scripting.Utils and the other in 
[System.Core]System.
It shouldn't matter much which ones do you use.

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.
