Hey Guys,
I have integrated a BING map onto my app, and it works okay, can see what I need to see.
My issue is when I want to add a push-pin or highlight where I am on the map, it returns an error when i select the Locate Me button.
It errors out on my .xaml.cs on the line
mapControl.Items.Add(p);
and the details : {"Operation not supported on read-only collection."}
Ill post the xaml.cs code below, if anyone can suggest a fix..only thing that's bugging me now.

loc = new GeoCoordinateWatcher(GeoPositionAccuracy.Default);
loc.StatusChanged += loc_StatusChanged;
}
if (loc.Status == GeoPositionStatus.Disabled)
{
loc.StatusChanged -= loc_StatusChanged;
MessageBox.Show("Location services must be enabled on your phone.");
return;
}
loc.Start();
}
void loc_StatusChanged(object sender, GeoPositionStatusChangedEventArgs e)
{
if (e.Status == GeoPositionStatus.Ready)
{
Pushpin p = new Pushpin();
p.Template = this.Resources["pinMyLoc"] as ControlTemplate;
p.Location = loc.Position.Location;
mapControl.Items.Add(p);
map.SetView(loc.Position.Location, 17.0);
loc.Stop();
}
}
