Images are not rendering in both iOS and Android

[sam33r786]

Description

I am attempting to use a CarouselView to show an Array of images using URLs stored alongside an entity but the doesn't show anything than an empty white square in both Android and iOS.

I have also added a standalone Image element with a hard-coded source to check if the issue was with my code or the framework but the issue remains.

            <CarouselView ItemsSource="{Binding CurrentRecord.ImageUrls}" IndicatorView="indicatorView" HeightRequest="300">
                <CarouselView.ItemTemplate>
                    <DataTemplate>
                        <Frame HasShadow="True"
                           BorderColor="DarkGray"
                           CornerRadius="5"
                           Margin="20"
                           HeightRequest="300"
                           HorizontalOptions="Center"
                           VerticalOptions="Center">
                            <Image Source="{Binding .}" 
                               Aspect="AspectFill"
                               HeightRequest="150"
                               WidthRequest="150"
                               VerticalOptions="Center"
                               HorizontalOptions="Center" />

                        </Frame>

                    </DataTemplate>

                </CarouselView.ItemTemplate>

            </CarouselView>
            <IndicatorView x:Name="indicatorView"
                   IndicatorsShape="Square"
                   IndicatorColor="LightGray"
                   SelectedIndicatorColor="DarkGray"
                   HorizontalOptions="Center"
                   Margin="0,0,0,40" />

            <!-- Standalong hard-coded image element-->
            <Image Source="https://en.wikipedia.org/wiki/Visual_Studio#/media/File:Visual_Studio_2013_EN.png" HeightRequest="200" WidthRequest="200" MinimumHeightRequest="200" MinimumWidthRequest="200" />

I have the same problem, only on the emulator everything works, but when you run it on the device - a blank square.

After several days of searching for solutions and experiments, I managed to find a solution to the problem. Add a datatype for the <DataTemplate> tag:

<CarouselView.ItemTemplate>
    <DataTemplate x:DataType="sys:String">
        <Image Source="{Binding .}"  />
     </DataTemplate>
</CarouselView.ItemTemplate>

and namespace: xmlns:sys="clr-namespace:System;assembly=mscorlib".

Maybe an analyzer should be added, so that the Visual Studio warnings about this situation?

Thanks for the workaround. I'll try and give that a go.

@7702244 I've tried your workaround and it doesn't seem to working for me for some reason.
