- Create corresponding class (inheriting from VectorLayerBase if vectors, or TileLayerBase if tile image layer)

- Implement base class abstract methods an especially LayerType property that must return the new enLayerType

In project BingMapsWPFViewer.ViewModel :

- Create View Model inheriting from LayerBaseViewModel
