Example

    string Results = "";

        //  Set a Bing Maps key before making a request 
        string key = "Bing Maps Key";
        RouteService.MajorRoutesRequest majorRoutesRequest = new RouteService.MajorRoutesRequest();
        //  Set the credentials using a valid Bing Maps Key 
        majorRoutesRequest.Credentials = new RouteService.Credentials();
        majorRoutesRequest.Credentials.ApplicationId = key;
        //  Set the destination of the routes from major roads 
        RouteService.Waypoint endPoint = new RouteService.Waypoint();
        endPoint.Location = new RouteService.Location();
        endPoint.Location.Latitude = 47.608;
        endPoint.Location.Longitude = -122.337;
        endPoint.Description = "Destination";

        RouteService.RouteServiceClient routeService = new RouteService.RouteServiceClient("BasicHttpBinding_IRouteService");
        RouteService.MajorRoutesResponse majorRoutesResponse = routeService.CalculateRoutesFromMajorRoads(majorRoutesRequest);
