I just upgraded my Xamarin plugin to 4.3.0.784, and now Visual Studio cries about NuGet not initialzing properly:
I uninstalled Xamarin, repaired Visual Studio, reinstalled Xamarin 4.2 and the problem went away. Curious, I then updated to 4.3 again, and the error came back. So something is wrong with this version.
I searched around and found this from a while ago

My teammate also updated to 4.3, but he does not have this problem. We are both running Visual Studio 2015 Update 3 Enterprise.
Is anyone else experiencing this issue?
