Creating a Windows app

If you’re interested in using Xamarin.Forms to target Windows, Windows Phone, or Windows 10 Mo-bile, you’ll need to become familiar with at least the rudiments of using Visual Studio to develop Windows applications:

In Visual Studio 2015, if everything is installed correctly, you should be able select File > New > Project from the menu, and in the New Project dialog, at the left, select Visual C# and Windows. You’ll see a hierarchy under the Windows heading something like this:

The first Universal heading under Windows is for creating a Universal Windows Platform application that can target either Windows 10 or Windows 10 Mobile. Select that, and from the center area select Blank App (Universal Windows) to create a UWP app.

The other two project types supported by Xamarin.Forms are under the Windows 8 header. The Universal item actually creates two projects—a Windows desktop application and a Windows Phone application with some shared code. For creating just a Windows application, choose Windows and then from the center section Blank App (Windows 8.1). For a Windows Phone application, choose Windows Phone and Blank App This creates a project that targets Windows Phone 8.1.

These are the three project types supported by Xamarin.Forms.

You should be able to build and deploy the skeleton application to the desktop or to a real phone or an emulator. If not, search the Microsoft website or online forums such as Stack Overflow.
