The "Xamarin.Forms.Build.Tasks.GetTasksAbi" task could not be loaded from the assembly , C:\Users\XXXX.nuget\packages\xamarin.forms\3.0.0.482510\build\netstandard2.0\Xamarin.Forms.Build.Tasks.dll. Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral

This is the cause:

Could not load file or assembly 'netstandard, Version=2.0.0.0, Culture=neutral

Starting with Xamarin-Forms 3, XF has moved to .Net Standard 2.0, so you need to create a library against .net standard 2.0.

Thanks for all the suggestions. I just updated Windows 10 and it worked. I had and old Windows build so I guess it was related to my Windows being outdated.
