I was wondering if there were any good examples that would show me how to execute a QueryFeaturesAsync call on a FeatureTable using a SpatialRelationship of Within. I've got some code wired up but it doesn't seem to be returning any results, when I know there should be.
Here's the code I'm currently using. An exception is getting caught - no elements in this sequence when I try to get the First item from the query results.
qp.Geometry = new Envelope(Location, Radius, Radius);
qp.SpatialRelationship = SpatialRelationship.Within;
FeatureQueryResult queryResult = await table.QueryFeaturesAsync(qp);
Feature ftr = queryResult.First();
catch (Exception ex)
string m = ex.Message;
