The instructions for WinPhone is out of date. The inherited FormsApplicationPage doesn't exist, instead, it should just be the default of public sealed partial class MainPage.
The XAML has also changed (not sure if that is on the website or not) to be
The linked documented is out-of-date - however it's not so much "wrong" as still referring to the Windows Phone 8 (Silverlight) platform support, rather than the newer WinRT support that is only now becoming the default in our project templates.
The details & instructions for the WinRT and UWP platforms are available here:
Minor updates have been made to the page to help prevent confusion -- thanks for bringing this to our attention. We'll make further updates when the new templates are fully rolled out.
Thanks - will these changes also be reflected in the github code? I found it confusing that there are two repos for forms, one using the "old" (Silverlight) and one using the "new" (WinRT)
Which repos are you referring to?
The main Xamarin.Forms repo is located at
and is gradually being updated so that all samples have all four Windows project types (Phone8SL, Phone8RT, Windows8RT, Windows10UWP). You'll find some samples in there currently have all four, but as Phone8SL was the "original" supported platform, it is the one that current exists in all samples.
This is also the repo that backs all the documentation and samples on https://developer.xamarin.com/samples/xamarin-forms/all/
The other repos we have with Xamarin.Forms samples are the book repos:
The first is rather out-of-date however Charles has made a big effort to ensure the second-preview samples are all updated to Xamarin.Forms 2.0 and include all fours Windows platforms (both the original Phone8SL _and_ the three newer ones).
From memory, aren't there some in the mobile-samples repo as well?
Generally there should not be - that repo is intended to highlight how Xamarin helps to leverage code sharing and native user-interfaces _without_ using Xamarin.Forms.
