Examples

C#
CircleFence cf = new CircleFence();

// set the radius (in miles - we can use similar properties to set
// the radius in meters and feet) and center location of the fence
cf.RadiusMiles = 2;
cf.Center = new LatLon(33.581353, -117.726979);

// draw the CircleFence on our map
myMap.Items.Add(cf);

The same effect can be achieved using XAML code by placing the following code snippet inside a Map object.

XAML
<GeoFence:CircleFence x:Name="cf"
    Center="33.581353, -117.726979"
    RadiusMiles="2"
/>
