Creating a UWP project for Xamarin

Question

I am trying to add UWP to my Xamarin project, as I have done with Windows Phone 8.1 . Unfortunately I first saw that Acr.XamForms.UserDialogs is not available on Windows.Phone 8.1 , until I after I had created it and trying to run it, as this error occurs .

I then tried to add an UWP project , but the 1st thing I found wierd, is that it creates 2 projects; project.UWP.Windows (Windows 8.1) and project.UWP.WindowsPhone (Windows Phone 8.1) . Do it have to create 2 projects or only one?

I followed this guide .

I continued, but then it could not find Xamarin.Forms.Platform.UWP . I am using Xamarin.Forms; version 2.2.0.45 Xamarin.Forms; version 2.2.0.45 and Visual Studio 2015 Enterprise on Windows 10 .

UPDATE
I figured out, I have choosen the Universal for Windows 8.1 , so the problem layed in there.
I created an UWP project now, but it still says Cannot resolve Assembly or Windows Metadata file 'Xamarin.Forms.Platform.WinRT.dll' and Type universe cannot resolve assembly: Xamarin.Forms.Platform.WinRT, Version=1.5.0.0, Culture=neutral, PublicKeyToken=null.

If you see in the setup on the right window it shows both Windows 8.1 and Windows Phone 8.1.

Window 8.1 is for windows application development. Which can be run on windows 8.1 PC's .

Windows Phone 8.1 is for Windows phone , this is windows mobile application development.
