I am trying to add WMS layer published on GeoServer using the code given below
var wmsLayer = new WmsLayer()
{
ID = "highways:sp_health_dh",
Url = "https://tnssdi.tn.gov.in/geoserver/wms",
SkipGetCapabilities = false,
Version = "1.1.1",
Opacity = 0.7,
DisplayName = "District Hospitals",
Layers = new string[] { "highways:sp_health_dh" }
};
map.Layers.Add(wmsLayer);
When I try to run the application, received the following error.
Unhandled exception at line 159, column 14 in http://localhost:60414/epathaigis.aspx

To resolve the error, I added crossdomain.xml in the root folder where the layers are published. Still I am getting the same error.
How can I resolve the above issue?
