I wanted to switch from PyCharm to Visual Studio for my Python (more specific: arcpy) development, since we do a lot of developing in VS and I figured it would be nice to have a single development environment. I was pleasantly suprised that Python was available out-of-the-box after installing VS. But would it recognize my arcpy sitepackage (which was already present in my C:\Python27\ArcGISx6410.3 directory, since ArcGIS for Desktop is installed on my system).
Guess what? No, it didn’t.
But then I came across this blogpost. And it totally was applicable to my situation. So, if you think VS doesn’t understand arcpy, wait a few minutes after your first try… Thank you, Cindy Williams, for saving me a lot of frustration.
