Fruit Benefits APP Using Master Detail Page In Xamarin.Forms Application For Android And UWP

Xamarin.Forms master detail page is a page, which manages two related pages of information – a master page that presents the items and a detail page that presents the details about the items on the master page.

After reading this article, you will learn how to use master detail page in Xamarin.Forms Application for Android and Universal Windows Platform with XAML and Visual C# in cross platform Application development with an example of Fruit Benefits app.

The following important tools are required to develop UWP.

  1. Windows 10 (Recommended).
  2. Visual Studio 2015 Community Edition (It is a free software available online).
  3. Using Visual Studio 2015 Installer, enable Xamarin (Cross Platform Mobile development and C#/.NET, while installing/modifying Visual Studio 2015.
