Today upgraded VS1015 Enterprise with Xamarin.forms via Nuget package manager.
All Forms Xaml pages in my project now display the 'InitializeComponent' error and all associated Xaml elements with X:Name also display the same error.
The solution does compile and debug run on all 5 projects Droid, iOS, Win, UWP.
I have cleaned and rebuilt the solution. SHut down and restarted VS but still the same.
I have read the old bugs and other solutions for the same issue back in 2014, 2015 such as checking csproj file is correct, that the .g.cs files are all present. I have modified and saved then built and deployed. still the same.
Worked fine this morning before I had an issue when testing my iOS device and had to upgrade Mac Xamarin to overcome that issue. Everything worked fine in VS until I decided to update packages. After upgrading Xamarin.forms to 22.214.171.124 from 126.96.36.199 the problem started.

Today rechecked Nuget and Xamarin.forms 18.104.22.168 was still present under updates. Checked and found that the original install only occurred to the PCL Project file and not the other projects, Droid, iOS, UWP and the two win8.1.
After reinstalling Xamarin.forms v22.214.171.124 and restarting VS the problem had gone away.
