Is there a third package manager now? There's the blessed one, NuGet, which most use, and Paket, which the cool kids and F# people use, but if there's another one out there I'm drawing a blank.
You can use the CLI as to do stuff. Not sure if it counts as package manager, but coming from Python, being faced with 3 different ways to install packages (I'm still not sure how environments/projects are supposed to work in .Net) certainly added to the confusion.
