\obj\x86\Debug\MainPage.g.i.cs(13,67,13,77): error CS0234: The type or namespace name 'WindowPage' does not exist in the namespace 'Xamarin.Forms.Platform.WinRT' (are you missing an assembly reference?)

The assembly is referenced?  Any idea?

(Universal Windows Project)
Comment 1 fraser.baldwin 2015-11-09 14:48:39 UTC
I did follow these steps:

Once you have that setup, you will want to:
● Add a new “Blank App (Universal Windows)” project to your existing Xamarin.Forms
solutions.
● Ensure the new project is configured to build and deploy in the configuration manager.
● Add the Xamarin.Form NuGet packages to the newly created project.
● Update Xamarin.Forms NuGets for another platform projects, and
● Configure the application by making the following changes to your UWP project code
Update App.xaml.cs
In OnLaunched under:
rootFrame.NavigationFailed += OnNavigationFailed;
Add:
Forms.Init (e);
Update MainPage.xaml
1. Remove all contents from the page.
2. Add a new xmlns of xmlns:forms=”using:Xamarin.Forms.Platform.WinRT” .
3. Update the root to <forms:WindowPage …> </forms:WindowPage>
Update MainPage.xaml.cs
public sealed partial class MainPage
{
public MainPage()
{
InitializeComponent();
LoadApplication (new App());
}
}
Reference Your Portable Class Library
Don’t forget to reference your Xamarin.Forms PCL (if you are using PCLs).

Please update to Xamarin.Forms 2.0 and on the new Universal Windows use this namespace

xmlns:forms="using:Xamarin.Forms.Platform.UWP"
