o Microsoft.Maps.MapControl.dll
Replace MainPage.xaml with the following code<UserControl x:Class="SilverlightMapControl.MainPage"   xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"   xmlns:d="http://schemas.microsoft.com/expression/blend/2008"   xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"   xmlns:map="clr-namespace:Microsoft.Maps.MapControl;assembly=Microsoft.Maps.MapControl"   mc:Ignorable="d"   d:DesignHeight="300" d:DesignWidth="400">   <Grid x:Name="LayoutRoot" Background="White">
        <Grid.RowDefinitions>            <RowDefinition Height="35" />            <RowDefinition Height="*" />        </Grid.RowDefinitions>        <Button x:Name="btnCreatePolygon" Width="100" Height="25" Content="Create Polygon" HorizontalAlignment="Left" Tag="false"               Click="btnCreatePolygon_Click"></Button>        <map:Map x:Name="MapWithPolygon" CredentialsProvider="your key" Mode="Road" Grid.Row="1" Grid.ColumnSpan="2">        </map:Map>
    </Grid>
</UserControl>
Add the following in MainPage.xaml.cs.private void btnCreatePolygon_Click(object sender, RoutedEventArgs e)
        {
            MapPolygon polygon = new MapPolygon();
            polygon.Fill = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Colors.Gray);
            polygon.Stroke = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Colors.Black);
            polygon.StrokeThickness = 1;
            polygon.Opacity = 0.7;
            polygon.Locations = new LocationCollection() {
            new Location(15,-15),
            new Location(15,15),
            new Location(-15,15),
            new Location(-15,-15)};
            MapWithPolygon.Children.Add(polygon);
        }
Build the solution.
