Problem: Using the .NET ADF Identify tool on a WMS service returns either no result or a URL
When using the Identify tool in the .NET ADF on a server object which contains a WMS service, the results window either does not display any values for the WMS layers or only provides a URL string.
ArcGIS Server doesn't support identification of a embedded layer that is from a WMS service.
Solution or Workaround
This is a known limitation of ArcGIS Server.
- WMS layer issues
- Can WMS Layers be embedded into another service using ArcMap Server or ArcGIS Server?
