Steven, Identify will not return features that are not part of the definition expression on a layer. One workaround you can try is to have another layer (same data source, no definition expression) but set the layer opacity to 0; since opacity will be ignored with identify... Identify features—ArcGIS Runtime SDK for .NET | ArcGIS for Developers, if you identify features on this new layer you will get the features you want. In this case you will only see the features returned by the definition expression, but you can identify all the features. Tony ... View more

Also make sure that the SpatialReference of your envelope matches that of your layer. ... View more

Mark, The MapView has some methods on it that you could use; try looking into  MapView.SetViewpointCenterAsync , or  MapView.SetViewpointScaleAsync. Doc on these methods can be found at: https://developers.arcgis.com/net/latest/wpf/api-reference/html/Methods_T_Esri_ArcGISRuntime_UI_Controls_MapView.htm A sample code can be found at: https://developers.arcgis.com/net/latest/wpf/api-reference/html/M_Esri_ArcGISRuntime_UI_Controls_MapView_SetViewpointScaleAsync.htm Hope this helps.

Dan, what results do you get when you try: MapPoint pt = new MapPoint(-12510471.4877441, 3975740.5774242762, new SpatialReference(3857)); var results = await MyMapView.IdentifyLayersAsync(MyMapView.LocationToScreen(pt), 1, false ); What version of the ArcGIS Runtime .Net API are you using? Thanks, Tony ... View more

Dan, Would you be able to provide the two geometries in Json and the e.Position value you used so we can try to reproduce the behavior? Thanks, Tony ... View more

Dan, Have you tried to decrease the "tolerance" value you provide to IdentifyLayersAsync(...).  From our Doc: "Tolerance: radius in points specifying how precise the identify operation should be. A value of 0 means that it should be extremely precise - only those features appearing at the exact coordinates should be returned. A value of 22 (a good default for touch displays which covers an average finger tap) means features appearing within a 44pt buffer can also be returned. Max value permitted is 100. " Thanks, Tony ...

Eric, try something like this: ``` AuthenticationManager.Current.ChallengeHandler = new ChallengeHandler( async (info) => { return await AuthenticationManager.Current.GenerateCredentialAsync(portalUri, UserName, Password); });   var portal = await ArcGISPortal.CreateAsync(portalUri, true , CancellationToken.None); ``` for portalUri use: new Uri(" https://<myname>.maps.arcgis.com ") ...
