CalendarStyle of DatePicker different than my custom CalendarStyle

I have a custom Calendar style and a custom DatePicker style.

Code in my MyCustomSkin.xaml (from my library project)

<Style TargetType="{x:Type Calendar}">
    <Setter Property="Background" Value="Red"/>
</Style>
<Style TargetType="{x:Type DatePicker}">
    <Setter Property="Background" Value="Green"/>
</Style>

They are both inside my MyCustomSkin.xaml ResourceDictionary (separate solution that generate a MyCustomSkin.dll) that I reference inside my application.

Code in my App.xaml (from my application)

<Application x:Class="WpfApplication1.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/MyCustomSkin;component/MyCustomSkin.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

Code in my MainWindow.xaml (from my application)

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow">
    <Grid>
        <DatePicker HorizontalAlignment="Right" />
        <Calendar HorizontalAlignment="Left"/>
    </Grid>
</Window>

When I create a Calendar in my application (without specifying any style), the background is red. When I am creating a DatePicker in my application (without specifying any style), the background is green but the background of its calendar is the system one (=> not red).

Why? I thougt that I was overriding all the system calendars with mine. Why is it applying the custom style for the Calendar but not on the Calendar of DatePicker?

Thank you!

Your MyCustomSkin.xaml should be:

<Style TargetType="{x:Type Calendar}" >
                <Setter Property="Background" Value="Red" />
            </Style>

            <Style TargetType="{x:Type DatePicker}" >
                <Setter Property="Background" Value="Green" />
                <Setter Property="CalendarStyle">
                    <Setter.Value>
                        <Style TargetType="{x:Type Calendar}" BasedOn="{StaticResource {x:Type Calendar}}"/>

                    </Setter.Value>
                </Setter>
            </Style>

DatePicker has a default CalendarStyle which will be applied on component initialization.
