Issue with 'ESRI.ArcGIS.Client.Geometry.Geometry' in WCF service

Hi There, I am having this issue with using Geomtry that is returned from a WCF service. As part of the service, I have added a service reference for the map service that I am using in this project. I am trying to return 'ESRI.ArcGIS.Client.Geometry.Geometry as a return type but when I assign the Geomtry to my result, it comes back with this error: 'Geometry' is an ambiguous reference between 'GIS.Services.Data.BoundaryMapService.Geometry' and 'ESRI.ArcGIS.Client.Geometry.Geometry'. I am not sure what needs to be done to resolve this issue. Appreciate any feedback. Thanks Jay

                ESRI.ArcGIS.Client.Geometry.Geometry resultGeometry = null;

                for (int i = 0; i < attributes.Values.Count(); i++)
                    if (attributes.Values is PolygonN)
                    {
                        PolygonN featureExtent = attributes.Values as PolygonN;
                        resultGeometry = featureExtent; // Error here...

                    }

You cannot mix two different geometry models. What you are essentially doing is assigning one type to a completely different type, which naturally isn't allowed. You will need to write some code that converts PolygonN into Client.Geometry.Polygon.

Thanks Morten for your feedback. I havent done much with Silverlight API but I am curious if here a way to get the vertices from PolygonN. This way I can get the vertices of the geomtry and pass it as a list. Are there are resources thst have sample showing how to do this. Thanks again. Jay

Sorry I don't know much about PolygonN. You might want to refer to the ArcObjects documentation and forums for that.
