I am trying to figure out a way to know if the parcel layer is indexed or not. Using the ESRI ArcGIS Runtime for .NET, is it possible to determine in code what attribute indexes exist for a FeatureTable? We are working on UWP.
It looks like can access this information from the REST endpoint of the feature service layer but we do not currently expose it via an API property on ArcGISFeatureLayerInfo class.
You could make the request yourself using C# and the ArcGISHttpClientHandler (which will help handle any authentication required).
