The Cool Windows 7 Selection in XAML

Here's the XAML to make a selection rectangle similar to the one in Win7:

        <Grid Height="22" Width="300" > 

            <Rectangle Stroke="#FF7DA2CE" RadiusX="2" RadiusY="2">

                <Rectangle.Fill>

                    <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">

                        <GradientStop Color="#FFDCEBFC" Offset="0" />

                        <GradientStop Color="#FFC1DBFC" Offset="1" />

                    </LinearGradientBrush>

                </Rectangle.Fill>

            </Rectangle>

            <Rectangle Margin="1" Stroke="#FFEBF4FD" RadiusX="2" RadiusY="2" Fill="{x:Null}">

            </Rectangle>

        </Grid>
