Image Slider CarouselView problems in Xamarin Forms (IOS)

I have read most of the questions posted here like this CarouselView not showing the data and Xamarin Form: Carousel View not showing on CarouselView but still me i get no luck, i am doing this common monkey example https://blog.xamarin.com/flip-through-items-with-xamarin-forms-carouselview/ but when i run on the simulator i see nothing, when i give it a background color it shows it .I even tried a simple example to populate list of numbers in a CarouselView but still it wasn't displaying anything.What is exactly the problem?

This was my expectation , but still no luck :

  1. Is it the pre-release of Xamarin.Forms.CarouselView which has the problem or because i see it has two versions i have to choose one ? (But i tried each of them but still no luck)
  2. Am i supposed to use CarouselView.FormsPlugin instead of the Above if so what clear protocol should i take to achieve this ?

My XAML

<Grid RowSpacing="0">
  <Grid.RowDefinitions>
    <RowDefinition Height=".3*"/>
    <RowDefinition Height=".7*"/>
  </Grid.RowDefinitions>
  <cv:CarouselView ItemsSource="{Binding Zoos}" x:Name="CarouselZoos">
    <cv:CarouselView.ItemTemplate>
      <DataTemplate>
        <Grid>
          <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height="Auto"/>
          </Grid.RowDefinitions>
          <Image Grid.RowSpan="2" Aspect="AspectFill" Source="{Binding ImageUrl}"/>
          <StackLayout Grid.Row="1" BackgroundColor="#80000000" Padding="12">
            <Label TextColor="White" Text="{Binding Name}" FontSize="16" HorizontalOptions="Center" VerticalOptions="CenterAndExpand"/>
          </StackLayout>
        </Grid>
      </DataTemplate>
    </cv:CarouselView.ItemTemplate>
  </cv:CarouselView>
  <!--List of Monkeys below-->
</Grid>

My C#

Model Class public class Zoo

{
    public string ImageUrl { get; set; }
    public string Name { get; set; }
}

MainActivity.cs

public class MonkeysViewModel
{
    public ObservableCollection<Monkey> Monkeys { get; set; }
    public ObservableCollection<Grouping<string, Monkey>> MonkeysGrouped { get; set; }

    public ObservableCollection<Zoo> Zoos { get; set; }

    public MonkeysViewModel()
    {

        Monkeys = MonkeyHelper.Monkeys;
        MonkeysGrouped = MonkeyHelper.MonkeysGrouped;
        Zoos = new ObservableCollection<Zoo>
        {
            new Zoo
            {
                ImageUrl = "http://content.screencast.com/users/JamesMontemagno/folders/Jing/media/23c1dd13-333a-459e-9e23-c3784e7cb434/2016-06-02_1049.png",
                Name = "Woodland Park Zoo"
            },
                new Zoo
            {
                ImageUrl =    "http://content.screencast.com/users/JamesMontemagno/folders/Jing/media/6b60d27e-c1ec-4fe6-bebe-7386d545bb62/2016-06-02_1051.png",
                Name = "Cleveland Zoo"
                },
            new Zoo
            {
                ImageUrl = "http://content.screencast.com/users/JamesMontemagno/folders/Jing/media/e8179889-8189-4acb-bac5-812611199a03/2016-06-02_1053.png",
                Name = "Phoenix Zoo"
            }
        };
    }
}

Ok , me too i had the same problem but this is how i solved mine but i don't know why.

STEP 1:

Check the Packages Folder under your projectname , right click on it and click add package , then search Xamarin.Forms.CarouselView then install it (version 2.3.0 pre 1).

STEP 2:

Check also under projectname.IOS and projectname.DROID the Packages Folder, also right click on it and click add package , then search Xamarin.Forms.CarouselView then install it (version 2.3.0 pre 1).

NOTE:

Install the same version Don't forget this.

Then run the App and see the output , hope it helps :-)

Happy Coding
