Windows Phone Tasks provide applications with the ability to integrate with services on the device. In this article I'll show you how use the CameraCaptureTask to allow your application to retrieve a photo or choose one in the WP galleries.

In the MainPage.xaml we insert a button (btnCameraCapture) and an image (image1) control:

<Grid x:Name="LayoutRoot" Background="Transparent">
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
<TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
<TextBlock x:Name="PageTitle" Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
</StackPanel>
<Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
<Button Content="Camera Capture" Height="77" HorizontalAlignment="Left" Margin="27,40,0,0" Name="btnCameraCapture" VerticalAlignment="Top" Width="243" Click="btnCameraCapture_Click" />
<Image Height="251" HorizontalAlignment="Left" Margin="26,153,0,0" Name="image1" Stretch="Fill" VerticalAlignment="Top" Width="340" />
</Grid>
</Grid>
