ok so here's another bug for david :) c# scripting components don't reference the proper System.dll. maybe we should get a bug tracker on...
so to answer ineyeseekay's question, System.IO.Ports might already be there, depending on whether you're using c# or vb.net scripting components. @visose i can imagine the pain to just add an unprintable polyline in .net when compared to rhinoscript... heard that there's some work going on in bridging this gap, can't wait for it to happen... glad to hear that automatic translations between c# and vb.net work nice - i'm stuck to c# due to old habits but now it might seem that publishing bi-lingual code is something to look forward to :)
