Any reason you're not using an ArcGIS server service? anyway you can't return arcobjects in a wcf service since it wouldn't know how to convert it into XML or json. You will need to define a datacontract class with some simple properties that you convert between in each end. I also wrote the following blogpost way back when which might be helpful: http://blogs.esri.com/esri/arcgis/2010/03/11/sending-geometry-between-silverlight-and-the-server-using-wcf/ This uses the arcgis wpf and SL geometries for transferring since these have a data contract and share the same one.
