as IList cannot just be instantiated like List.
@PanPawel_1 : find a solution to create a working StrongBox[IList[ClosestPointsPairBetweenTwoCurves]] in ironpython in my other post:

Help with Curve method ComputeClosestPoints

@Jean-Marc I think asking on the friendly and helpful pyRevit forum is a good idea, too. @rtorrez : for the case of the result out argument it is indeed more tricky than the common strongbox or typed list examples one would find in usual rvtapi snippets. to get to the working ironpython version I wrote it in c# and tried to do the same in ironpython. so here is the c# snippet: IList<ClosestPointsPairBetweenTwoCurves> results = new List<ClosestPointsPairBetweenTwoCurves>(); so a new …
