Hello,
First, I am surprised that my Pickers BindingContext inherites from their parent StackLayout but not from the ContentPage. Is that normal?
Second, a picker inherites from its parent StackLayout BindingContext after the SelectedIndex is set. How to set the SelectedIndex after the Picker has inherited from its parent BindingContext?

this is my XAML code:

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="AlmicantaratXF.Views.SightPage"
             xmlns:i18n="clr-namespace:AlmicantaratXF.Views;assembly=AlmicantaratXF"
             xmlns:viewModels="clr-namespace:AlmicantaratXF.ViewModels;assembly=AlmicantaratXF"
             xmlns:converters="clr-namespace:AlmicantaratXF.Converters;assembly=AlmicantaratXF"
             xmlns:behaviors="clr-namespace:AlmicantaratXF.Behaviors"
             Title="{i18n:Translate titleSight}"
             BackgroundColor="{StaticResource AppBackgroundColor}">
    <!--   Title="{i18n:Translate titleSight}">     -->

    <ContentPage.BindingContext>
        <viewModels:SightPageViewModel/>
    </ContentPage.BindingContext>

    <ContentPage.Content>
        <StackLayout  Orientation="Vertical"
                      Margin ="0"
                      Padding="0">

<!--  If the StackLayout.BindingContext is commented out, the Pickers binding does not work
        as it is not commented out, the SightPAgeViewModel constructor is executed twice: one by ContentPage, second by StackLayout -->

            <StackLayout.BindingContext>
                <viewModels:SightPageViewModel/>
            </StackLayout.BindingContext>

                <Picker
                    x:Name="PickerBodyType" 
                        Title="Body Type"
                        ItemsSource="{Binding BodyTypes, Mode=TwoWay}"
                        SelectedIndex="1"
                        WidthRequest="120"

                    <!--<Picker.BindingContext>
                        <viewModels:SightPageViewModel/>
                    </Picker.BindingContext>-->
                </Picker>

                <Picker 
                        x:Name="PickerLimb"

Hi guys, i'm a xamarin newbie. I have developed a simple Forms app to display some particular html files (by webview). To store the files i've used embedded resource. Now i need to implement a mechanism to updates of that files...so i've developed an asp net mvc web api. When i call it returns to me a zipfile with updated contents (they must be stored in the sd card). In your opinion, what is the best way to handle a lot of html files stored in the sd storage? Must i copy them to Asset (or assets are write only..?) to visualize them?

Thank you very much for your advices, i'm a little bit confused.
