Unable to start Build 4.3.0.664 agent. when building iOS apps

Starting up Visual Studio 2017 RC today, opening a Xamarin Forms application and building I am presented with…

“Unable to start Build 4.3.0.664 agent. when building iOS apps”

Uggh, yes another build issue.  So before I can do anything I must once again work through connectivity, emulator, build errors.  Note, if you venture to go in this direction with your learning/career patience is a must.

1.) Delete this folder:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE\Extensions\Xamarin

2.) Delete this folder:
C:\Users\{username}\AppData\Local\Microsoft\VisualStudio\15.0_3bcaeaa8 (this hash needs to correspond to the instance of VS 2017 you are using)

 

I am using 2017 RC.4+26206.0 right now by the way.
