Visual Studio 2015 : Windows Phone part

Question

I want to create a new Cross-Platform project using C# in Visual Studio 2015 i get just the Android and iOS parts. So how i can add the Windows Phone part in my project ?

Answer 1

You have to install the Windows Phone SDK. And then you can add a Windows Phone Project to your solution File > New > Project

Answer 2

You need to have all of the necessary Windows Phone SDK bits installed for the projects to be added. If you can't create a stand-alone Windows Phone 8/8.1 project in Visual Studio, then Xamarin.Forms won't be able to create the necessary projects.

Windows Phone 8 SDK

Windows Phone 8.1 SDK

If you already have these installed, then you can just add the needed projects to the solution, though the Cross-Platform project template should have created them for you.

Answer 3

Adding a Windows Phone App

(Follow the link for a properly formatted view of these instructions)

Firstly, if you used the Xamarin.Forms PCL template, update the profile, then follow the instructions below:

1 right-click on solution > Add > New Project... and add a Blank App (Windows Phone)

2 right-click on the newly created project > Manage NuGet Packages... and add the Xamarin.Forms package.

3 right-click on project > Add > Reference and create a project reference to the shared Xamarin.Forms application project.

4 Edit App.xaml.cs to include the Init() method call, in the OnLaunched method around line 67:

// add this line
Xamarin.Forms.Forms.Init (e); // requires LaunchActivatedEventArgs
// above this existing line
if (e.PreviousExecutionState == ApplicationExecutionState.Terminated) {}

5 . Edit MainPage.xaml - change the root element

<forms:WindowsPhonePage
...
   xmlns:forms="using:Xamarin.Forms.Platform.WinRT"
...
</forms:WindowsPhonePage>

6 . Edit MainPage.xaml.cs to remove the : PhonePage inheritance specifier for the class name.

public sealed partial class MainPage // REMOVE ": PhonePage"

7 . Still in MainPage.xaml.cs, add the LoadApplication call in the MainPage constructor (around line 28) to start your Xamarin.Forms app:

// below this existing line
this.InitializeComponent();
// add this line
LoadApplication(new YOUR_NAMESPACE.App());

8 . Double-click Package.appxmanifest to set these capabilities that are often required:

Internet (Client & Server)

9 . Finally, add any local resources (eg. image files) from the existing platform projects that are required.
