I run these commands to create the Nuget packages, then move them into my local nuget folder.
`Go to the Xamarin.Forms folder in Powershell, then allow for all scripts to be run with this:
Set-ExecutionPolicy Unrestricted -Scope CurrentUser -Force
./Build.ps1 -Target NugetPack
`
However, the nuget packages it makes aren't seen by VS 2017.
In previous versions of Xf (3.4 and lower) I used to run the batch file : .create-nuget.bat it would create a version 9.9.9 which I could then upgrade my solution to for testing/debugging.
