<Label Text="tesyt"
HorizontalOptions="Center"
VerticalOptions="CenterAndExpand"></Label>
<CarouselView HorizontalScrollBarVisibility="Never" BackgroundColor="Blue"
x:Name="carousel"
HorizontalOptions="CenterAndExpand"
VerticalOptions="CenterAndExpand"
HeightRequest="500"
> <CarouselView.ItemsLayout>
<LinearItemsLayout Orientation="Horizontal" ItemSpacing="0"/>
</CarouselView.ItemsLayout>
<CarouselView.ItemsSource >
<x:Array Type="{x:Type Label}">
<Label Text="tesyt" TextColor="Green" Margin="10,0,0,0"
></Label>
<Label Text="tesyt" TextColor="Brown"></Label>
</x:Array>
</CarouselView.ItemsSource>
</CarouselView>
</StackLayout>

If you want to set item center in carouselview, you can set HorizontalOptions="CenterAndExpand" and VerticalOptions="CenterAndExpand" for item in carouselview datatemplate.
And I find there are some error for carouselview.itemsource, you can refer to x:Array markup extension firstly, you can also take a look the following code:
<CarouselView
x:Name="carousel"
BackgroundColor="Blue"
HeightRequest="500"
HorizontalOptions="CenterAndExpand"
HorizontalScrollBarVisibility="Never"
VerticalOptions="CenterAndExpand">
<CarouselView.ItemsLayout>
<LinearItemsLayout ItemSpacing="20" Orientation="Horizontal" />
</CarouselView.ItemsLayout>
<CarouselView.ItemsSource>
<x:Array Type="{x:Type x:String}">
<x:String>mono</x:String>
<x:String>monodroid</x:String>
<x:String>monotouch</x:String>
<x:String>monorail</x:String>
<x:String>monodevelop</x:String>
<x:String>monotone</x:String>
<x:String>monopoly</x:String>
<x:String>monomodal</x:String>
<x:String>mononucleosis</x:String>
</x:Array>
</CarouselView.ItemsSource>
<CarouselView.ItemTemplate>
<DataTemplate>
<StackLayout>
<Frame
Margin="20"
BorderColor="Red"
CornerRadius="5"
HasShadow="True"
HeightRequest="50"
HorizontalOptions="Center"
VerticalOptions="CenterAndExpand">
<Label
HorizontalOptions="CenterAndExpand"
Text="{Binding .}"
VerticalOptions="CenterAndExpand" />
</Frame>
</StackLayout>
</DataTemplate>
</CarouselView.ItemTemplate>
</CarouselView>
