How do i add UWP to xamarin forms in VS2019?

I try to create a new project(xamarin form) in vs2019, and discovered that the UWP template is missing.
I created the project in vs2017 yet it did not work. now I have added a UWP project to the xamarin form app created using vs2019, how do I link them, how do I connect(refrence) the UWP to the portable library?
I want to make use of the portable library in xamarin forms that ha UWP in it, like vs2017 versions
In VS 2019 version 16.0.0 UWP head project have been removed from the Xamarin.Forms app template. However, if you install latest version of VS 2019 (16.0.1) that option should be available to you. According to the release notes:
Add option for Windows (UWP) platform when creating new Xamarin.Forms project from 'Mobile App (Xamarin.Forms)' project template.
Other then that you could just simply add UWP as a separate project and set it up for Xamarin.Forms.

Xamarin Forms Android Compile Error

I'm trying to update my Xamarin Forms app to the latest Xamarin Forms and target the Android version against 7.1. After updating the build and target framework to 7.1 I'm getting the following compile time error:
/Users/austingrigg/Projects/ArtCloud/Droid/ERROR: Error APT0000: In AppBarLayout, unable to find attribute android:keyboardNavigationCluster (APT0000) (ArtCloud.Droid)
I'm using Visual Studio for Mac (7.3), Xamarin Forms 2.5.0.121934, and Xamarin Support Libraries 25.4.0.2
Make sure ALL of your Nugets are the same version. Open up your packages.xml and double check, then do a full clean/rebuild and try to delete your bin/obj folders.

What is the difference when using IPlatformInitializer In Prism

I've recently started to learn how to use Prism on Xamarin Forms, and I was seeing both Xamarin Studio and Visual Studio.
I created a project in Visual Studio and Xamarin Studio and noticed that in the Visual Studio Template Pack the same UnityApp Project differ with the Xamarin Studio version. In Visual Studio the App class constructor has a parameter of type IPlatformInitializer while the Xamarin Studio version does not.
I will like to know what is the difference between them and when to use each one ?
The Xamarin Studio Templates have not been updated because my Mac went down :)
You only need to use the IPlatformInitilizer if you want to register platform specific services. It's not required.
