Map interaction client/Layer visibility

The visibility of each layer is controlled individually through each layers Visibility property, IMariaInternalLayer.Visible.

To select layers to be displayed, first add a layers property to the main view model (MariaWindowViewModel):

public ObservableCollection<IMariaLayer> LayersDisplay
{
    get { return new ObservableCollection<IMariaLayer>(Layers);}
}

Then, add a list box with check items your XAML:

<ListBox Name="lstLayers" Height="Auto" Margin="2" 
             ItemsSource="{Binding LayersDisplay}" >
    <ListBox.ItemTemplate>
        <DataTemplate>
            <CheckBox Width="Auto" 
                      Content="{Binding Path=Name}" 
                      IsChecked="{Binding Path=Visible, Mode=TwoWay}" >
            </CheckBox>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

Running your application, you should be able to turn the different layers on/off !
