Hi,
I am trying to find a way to create graphics and convert those graphics to features (shapefile). Users should be able to draw graphics like point/line/polygon on surface and all those graphics should be converted to a shapefile in a workspace folder. Any help is much appreciated. Thanks

I don't know if I am going to be dissapear after this answer, so tell my family that I love them.......
I face a similar problem, but let me tell you that ArcGIS Runtime is quite limited....(I miss ArcObjects..sigh)...
I used DotSpatial library, to be more specific, DotSpatial.Data, you can download it from NuGet.
the process was to iterate over the graphics an use the Dotspatial to create each feature
var layer = this.MyMap.Layers["MyLayer"] as ArcGISLocalFeatureLayer; FeatureTemplate lineLayerTemplate = null; if (layer.LayerInfo.Templates != null && layer.LayerInfo.Templates.Count > 0) { lineLayerTemplate = layer.LayerInfo.Templates.FirstOrDefault().Value; } var featureSet = new DotSpatial.Data.FeatureSet(DotSpatial.Topology.FeatureType.Line); if (lineLayerTemplate != null && lineLayerTemplate.PrototypeAttributes != null) { foreach (var prototypeAttribute in lineLayerTemplate.PrototypeAttributes) { // the purpose of this is to create the columns that will apper in the shp file featureSet.DataTable.Columns.Add(new DataColumn(prototypeAttribute.Key as String)); } } foreach (var graphic in layer.Graphics) { var newPaths = new List<LineString>(); foreach (var path in (graphic.Geometry as Polyline).Paths) { var vertices = new List<Coordinate>(); for (int i = 0; i < path.Count; i++) { vertices.Add(new Coordinate(path[i].X,path[i].Y,path[i].Z,path[i].M)); } // LineString is from DotSpatial...like a PolyLine in Runtime var newPath = new LineString(vertices); newPaths.Add(newPath); } // Multiline is from DotSpatial var geom = new MultiLineString(newPaths); var feature = featureSet.AddFeature(geom); feature.DataRow.BeginEdit(); foreach (var attribute in graphic.Attributes) { feature.DataRow[attribute.Key] = attribute.Value; } feature.DataRow.EndEdit(); } featureSet.Projection = ProjectionInfo.FromEpsgCode(layer.SpatialReference.WKID); featureSet.SaveAs(@"C:\shptest.shp",true);enjoy
