After several hours finally managed to get it to work:

Still not sure exactly what a targeting pack is - and why VS couldn't install it but I manually installed this package and managed to get it to work:

• Manually installed: Microsoft .NET Framework 4.6.2 Developer Pack and Language Packs https://www.microsoft.com/en-us/download/details.aspx?id=53321

Other things I did that may have contributed to the solution:

• I rebooted
• I removed all files in C:\ProgramData\Microsoft\VisualStudio\Packages - actually I moved them to an OLD folder and later deleted them. You will see packages downloaded here after you restart the install.
• I had previously created a symbolic link from %ProgramData%\Package Cache to another drive to save space (https://superuser.com/questions/455853/can-i-delete-the-folder-c-programdata-package-cache). This symbolic link didn't seem to work anymore leaving me with some files in %ProgramData%\Package Cache and the rest in the other drive. I moved them over and recreated the link. If this is something you did to save disk space and forgot then that could contribute towards a failed solution.

Something above fixed the issue and I now have XAML back again.

Note: The VS2017 RC1 does not support offline installation so that was another avenue I explored and gave up on. The command line switches currently do NOTHING.

I believe the package I needed is the following one but not absolutely sure.

C:\ProgramData\Microsoft\VisualStudio\Packages\Microsoft.PortableLibrary.TargetingPack.Msi,version=15.0.25719.0
