You are correct, need the .NET SDK, and Extensions to build modules with Visual Studio Code. It’s been a while since I’ve done .NET, I think version 4 had the compiler, you could build with notepad and the command line ugh
BTW, I’ve had companies reach out to me to support zero-install Python packages for AutoCAD. They wanted to validate the modules, and block PIP. Basically it’s:
1, Grab Python embedded package from the Python site, it’s a minimal, portable zipped interpreter for Windows.
2, add the most commonly used packages, pyrx, pyopenxl, pypdf, genre specific tools, like shapely, or gdal
3, deploy it as a .bundle.
I've been meaning to write something about this, lazy i guess lol
