I’m new to C# sharp scripting, i am developing a simple plugin that outputs the top and bottom surface of a geometry but i seems there’s an error somewhere in the code that i haven’t managed to locate. When the plug in is brought into Grasshopper and i plug a brep in it, i get the error in the image bellow. Can someone please help me out. I’m also attaching the script for the plug in. I’m working in VisualStudio 2022 btw.
