Update Esri SOAP to REST

Question

I'm new to ArcObjects, not a GIS professional so please be patient with my lack of GIS knowledge. I have an .Net Web application with ESRI.ARCGIS.SOAP references, looking to update them with rest. I tried to use esri.arcgisruntime but it was not supported in Asp.net web application project How can I use REST in below code? ESRI.ArcGIS.SOAP.GeometryServerProxy serviceURL= new ESRI.ArcGIS.SOAP.GeometryServerProxy(); serviceURL.URL="Some Service URL"; ESRI.ArcGIS.SOAP.SpatialReference inputSpatialReference = new ESRI.ArcGIS.SOAP.ProjectedCoordinateSystem(); inputSpatialReference.WKID = 3857; inputSpatialReference.WKIDSpecified = true; ESRI.ArcGIS.SOAP.SpatialReference outputSpatialReference = new ESRI.ArcGIS.SOAP.GeographicCoordinateSystem(); outputSpatialReference.WKID = 4326; outputSpatialReference.WKIDSpecified = true; PointN pnt = new PointN(); pnt.X = X; pnt.Y = Y; Geometry[] inputGeometry = new Geometry[] { pnt }; ESRI.ArcGIS.SOAP.GeoTransformation geoTransformer = new ESRI.ArcGIS.SOAP.GeoTransformation(); geoTransformer.WKID = 2236; ESRI.ArcGIS.SOAP.EnvelopeN envelope = new EnvelopeN(); envelope = null; Geometry[] outputGeometry = serviceURL.Project(inputSpatialReference, outputSpatialReference, false, geoTransformer, envelope, inputGeometry); foreach (PointN item in outputGeometry) { xyCoord= item.X.ToString() + "," + item.Y.ToString(); }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi,

There is Out-of-box ArcGIS REST API which has Geometry service with Project operation.

Project—ArcGIS REST API: Services Directory | ArcGIS for Developers

you could send http request to API with any language, .net as well. No need Arcobject in your case.

cheers,
