diff between Update 2 (right side) and Update 3 (left side)

In a nutshell after installing Visual Studio Update 3, UWP no longer installs on phone.

From my comments here, https://forums.xamarin.com/discussion/70249/after-visual-studio-update-3-xamarin-4-1-1-3-cannot-deploy-to-windows-uwp-phone-or-8-1-phone-emula 

"Having the same issue here, update 2 still works fine.

I'm too dumb to extract and decipher the "Field Medic" reports to see what's going on but I'm thinking it's a dependency issue similar to here http://stackoverflow.com/questions/38594736/uwp-app-package-created-with-visual-studio-2015-update-3-wont-install-on-phone"

@Randy, if you have not already done so, could you please try updating the UWP SDK to see if that helps?

Last Friday, Randy sandboxed and upgraded Xamarin to the latest 'stable' channel and the issue seemed to go away on it's own.
Randy is planning to also try this on the production machine, but at this time, we are NOT blocked.
Comment 3 Randy 2016-09-22 16:47:37 UTC
Here's the latest:

Production machine still has the UWP install issue on the phone. Sandbox machine does not have the issue.  These machines are not exact replicas which explains why one installs and the other does not.  I thought I had updated the sandbox to Visual Studio Update 3, but apparently not.  I have uninstalled and reinstalled the UWP SDK's several times.

Production specs:
Windows 10 SDK 10.0.10586.212
Windows 10 SDK 10.0.26624
Visual Studio Version 14.0.25431.00 Update 3

Sandbox specs:
Windows 10 SDK 10.0.10586.212
Windows 10 SDK 10.0.10586.15
Windows 10 SDK 10.0.26624
Visual Studio Version 14.0.25123.00 Update 2

This issue mysteriously fixed itself on the hardware after an OS update on the phone hardware.  There was obviously a dependency missing on the phone hardware, but not sure why Visual Studio would not install this dependency.
