Steps to reproduce:
1. Try to open a storyboard file
The iOS storyboard designer launches.
A message box shows with the following error: The type initializer for 'Xamarin.Designer.BaseStyles' threw an exception.
See the attached ActivityLog.xml file because it's full of errors saying that there are Xamarin dlls missing and can't be loaded with MEF.
I've re-run the installation three times after rebooting my computer, no change. The installation package is incomplete.

Beginning of rant:
I'm starting to become afraid of installing "the next/latest version" of Xamarin, because almost every time I choose to do so, something is completely messed up.
I've already lost half a day of work trying to find out what "I" did wrong, only to come to the conclusion that it's you, again. So unless the "beta" channel version works, I'm screwed.
I still have a previous version installed at home on VS2017, so I'll work from home next week. Hopefully it will still be compatible with the version installed on the MacBook, since I also updated your stuff on it...
Please, this happens too often, you need to test your stuff better.
End of rant.
Well this is completely messed up, checking for beta and alpha channel updates yields NO UPDATES for Xamarin, only "Workbooks..." and "iOS Simulator"... So Xamarin doesn't even recognize that it's installed or there is no beta/alpha version?
I think I need an aspiRIN for my xamaRIN...
