<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
            xmlns:local="clr-namespace:AppX.Pages"
            x:Class="AppX.TabPage">

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="AppX.Pages.Home" Title="Home" Icon="home_icon.png">
    <ContentPage.Content>
        <StackLayout HorizontalOptions="Center" VerticalOptions="CenterAndExpand">
            <Label Text="Welcome to Home Page!" />
        </StackLayout>
    </ContentPage.Content>
</ContentPage>
