I have a WPF application (runtime 100.3) which has a base map and one feature layer. When I attempt to edit the vertices of the geometry (polygons) on my feature layer with the sketcheditor I am getting the following error:
Value does not fall within the expected range. at Esri.ArcGISRuntime.Geometry.Part.AddPoint(MapPoint point)
at Esri.ArcGISRuntime.UI.SketchEditor.AddVertexToPartCollection(MapPoint mapPoint, VertexPosition vertexPosition)
at Esri.ArcGISRuntime.UI.SketchEditor.AddPoint(MapPoint mapPoint)
Any suggestions on how to solve this would be appreciated.
