<Window x:Class="KinectSdkDemo.MainWindow"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="769" Loaded="Window_Loaded" Closing="Window_Closing" xmlns:my="clr-namespace:Microsoft.Samples.Kinect.WpfViewers;assembly=Microsoft.Samples.Kinect.WpfViewers">
    <Grid Height="381">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="354*" />
            <ColumnDefinition Width="393*" />
        </Grid.ColumnDefinitions>
        <my:KinectSensorChooser HorizontalAlignment="Left" Margin="330,123,0,0" Name="kinectSensorChooser1" VerticalAlignment="Top" Width="328" Grid.ColumnSpan="2" />
        <Image Height="240" HorizontalAlignment="Left" Name="image1" Stretch="Fill" VerticalAlignment="Top" Width="320" />
        <my:KinectColorViewer HorizontalAlignment="Right" Name="kinectColorViewer1" VerticalAlignment="Top" Height="240" Width="320" Kinect="{Binding ElementName=kinectSensorChooser1, Path=Kinect}" Grid.Column="1" />
    </Grid>
</Window>
