Circular Reference with Complex Type

I have created a webservice that returns a complex type.  This is the xml that is returned from the webservice:

<NinjaRouteEntity xmlns="http://tempuri.org/">
  <Entity NinjaRouteID="1" xmlns="">
    <AlwaysFetchToRegion>False</AlwaysFetchToRegion>
    <TimeFrameReturnsNewIfNotFound>True</TimeFrameReturnsNewIfNotFound>
    <AlwaysFetchFromRegion>False</AlwaysFetchFromRegion>
    <EntityCollectionReference PropertyName="PointCollectionViaNinjaRouteVector">
    ...
