MVVM at first can be a pretty intimidating concept but what will ultimately end up happening is you'll be doing without thinking about it.  Remember that MVVM is to separate the business logic from the view, when we look at the MapView it is a view, its to know of the viewmodel but not of the model, so you would not want to access parts of the model (i.e. Layers, Service Tables) via the view, but you would access them via the viewmodel.  With that said I think that what your attempting above needs another look.  Is it that you would like to set the an Overlays datacontext to the graphic???  It would be beneficial to see some more code too if that's possible.  Antti had done a session with Branscombe on how to make the move over from the WPF to .NET, it is some work and I am still making the move but I have found that the esri video's can help, just look up runtime .net ...

Got it, of course you were right.  I looked through the examples and found the key , you guys used _isMapReady Bool-- That did the trick.  Thanks ... View more

I had migrated a project over, things were fine were some time.  Then one day .... had this same issue... restarted, cleaned, rebuilt, even re installed the sdk.... nothing worked. Then went back to it a couple of days later ..... and it was fine ..... not sure what happened but all is well now, I would not be surprised if I saw this error again.  I'll let you know if I find the magic trick that I did ...

Yeah I think that I have found a workaround..... all was going well and actually started to do a lot of moving.   so far found that the one of the best ways to interact with the Mapview is to just touch it in the codebehind..... goes against all of my MVVM (but who says you can't have some codebehind--use what works right:)_)  Also have events tied within codebehind too.  Now a big problem.  In the old WPF Runtime, when users moved the mouse over their map it would fire on the feature layer mouse over event, do lookup on attributed info, then report what Township range the users cursor was in.  Trying to replicate this behavior in the new Runtime and have this so far....             //Screen Position needed for hit testing and the current Map Screen Point             var screenPosition = e.GetPosition(WrmsMapView);             #region Get the Lat and Long of the map and update the UI             var latLongPosition = GeometryEngine.Project(WrmsMapView.ScreenToLocation(screenPosition),                 SpatialReferences.Wgs84);             MouseCoordinates.UpdateLatLongHud(latLongPosition as MapPoint);             #endregion             var legalHudRows = await LegalHudFeatureLayer.HitTestAsync(WrmsMapView, screenPosition);             if (legalHudRows != null && legalHudRows.Length > 0)             {                 try                 {                     var legalHudHitFeatures = await LegalHudFeatureLayer.FeatureTable.QueryAsync(legalHudRows);                     returnedLegalFeature = legalHudHitFeatures.FirstOrDefault();                     MouseCoordinates.UpdateLegalHud(returnedLegalFeature);                 }                 catch (Exception)                 {                     MessageBox.Show(                         "There was an error whike attempting to get the Rows Collection Attributed information");                 }             } Problem is that the mouse move events seem to be firing too fast.... get an instant crash within my application and Visual Studio doesn't even catch the exception.... really scratching my head on this one.... must admit also pretty curious.... why not just have Events on Feature Layers, Graphics, etc.??  I understand having succinct code but I feel that the events that existed with the WPF Runtime were extremely useful while applying MVVM  I have also taken the time to look over the Runtime Examples and the map tapped events will be great for a lot of things and perhaps I need to go back to the drawing board on this problem.  Any suggestions ?? ...

Here is the code for the Location, I have tried this on an Ipad 2 and also an Air 2 with the same Results-publishing to Android works fine though .... Save there is no Compass support on Android. I have removed the specific server as were not to make the Services Public Quite yet, Also Removing the s out of HTTPS: works?? the services have had the token removed and seem to work fine just using http?  This is odd because in the other runtimes this will not work (iOS, Android and .Net)... hmmmm Thanks for the speedy response back import QtQuick 2.1 import QtQuick.Controls 1.0 import QtQuick.Dialogs 1.2 import QtQuick.Window 2.0 import QtQuick.Layouts 1.1 import ArcGIS.Runtime 10.3 import ArcGIS.Runtime.Toolkit.Dialogs 1.0 import QtPositioning 5.3 import QtSensors 5.3 ApplicationWindow {     id: appWindow     width: 320     height: 480     title: "WrmsLite" Rectangle{     anchors.fill: parent     property int hitFeatureId:0     property variant attrValue     property real scaleFactor: 1     property bool settingsView: true     states:[     State{             name:"Settings"             when:settingsDisplay             changes:[                 PropertyChanges {                     target: settingsDisplay                     anchors.fill:parent},                 PropertyChanges{                     target:mainMap                     visible:false}             ]         }     ]     Rectangle{         id:settingsDisplay         anchors.fill: parent         color:"white"     }     GeodatabaseFeatureServiceTable{        id:incidentsFeatureService        url:"https://SERVER/arcgis/rest/services/WRMS/Incidents/MapServer/0"     }     Map{         property Point locationPoint: Point{             property bool valid: false             spatialReference: SpatialReference{                 wkid: 4326             }         }         id:mainMap         anchors.fill: parent         ArcGISTiledMapServiceLayer{             id:basemap             url:"http://Server/arcgis/rest/services/USA_Topo_Maps/MapServer"         }         ArcGISDynamicMapServiceLayer{             id:publicOwnership             url:"https://Server/arcgis/rest/services/WebMercator/PublicOwnership/MapServer"             opacity: 0.4         }         ArcGISDynamicMapServiceLayer{             id:plss             url: "https://Server/arcgis/rest/services/WebMercator/PLSS/MapServer"         }         ArcGISDynamicMapServiceLayer{             id:lightning24             url:"https://Server/arcgis/rest/services/WebMercator/Lightning24hours/MapServer"         }         //ArcGISDynamicMapServiceLayer{            // id:incidents            // url:"https://Server/arcgis/rest/services/WRMS/Incidents/MapServer"         //}         FeatureLayer{             id:incidentsFeatureLayer             featureTable: incidentsFeatureService         }         positionDisplay{             compass:Compass{                     id:compass                 }                 positionSource: PositionSource{                 id:positionSource                 onPositionChanged: {                     mainMap.locationPoint.valid = position.latitudeValid&&position.longitudeValid;                     mainMap.locationPoint.x = position.coordinate.longitude;                     mainMap.locationPoint.y = position.coordinate.latitude;                     locationPointChanged();                 }             }                 onError: {                     console.log("There was an error with the Positional Display...
