WMS Issue/Debug

EdwardJakubowski

Hello,  I'm trying to figure out why a particular WMS Layer/Service will not show up on the MapView.  I've tested the same WMS URL with other map tools(IE, WorldWind), which seem to support it.  However, when I try to use it in ArcGIS 10.2.7 I can't seem to get it to display anything and it doesn't report and noticeable logs or errors.  How can I debug the WmsLayer and figure out what's going on?  Below is an example, the WMS server I'm trying to get working is internal.  I do know the code can work with other WMS sites, it's just not working on the one I need it to work with. Any ideas why?  Would it have issues dealing with self-signed certs?

public partial class MainWindow : Window
{
public MainWindow()
{
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; }; //ignore bad ssl
InitializeComponent();
}

private void MyMapView_LayerLoaded(object sender, LayerLoadedEventArgs e)
{
if (e.LoadError == null)
return;

Debug.WriteLine(string.Format("Error while loading layer : {0} - {1}", e.Layer.ID, e.LoadError.Message));
}
private void addWMSBtn_Click(object sender, RoutedEventArgs e)
{
//String wmsURL = "http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi";
String wmsURL = "https://wserver/wms?TYPE=population";
var wl = new Esri.ArcGISRuntime.Layers.WmsLayer(new Uri(wmsURL));
MyMapView.Map.Layers.Add(wl);
wl.IsVisible = true;
}
}

OK, I think I figured out what the bug or issue is.  Apparently it counts the basemap layer as a layer, and once that spatial reference is set in the map it won't use the WMS Layer's spatial reference.  Is there a way to force it to use more than one layer with different spatial references?  Currently I was able to get it working by creating a new map with the correct spatial reference...

MyMapView.Map = new Map()
{
  SpatialReference = new SpatialReference(4326)
};

MyMapView.Map.Layers.Add(wl);
