How to use Bing Maps geocode REST services

GetLocation.cs

// Legacy Bing geocoding SOAP services were recent shut down after being replaced by the REST services
// so, you need to migrate your app to use the REST services. 
//
// If your application uses .NET you will likely find this library useful:
// 'Bing Maps REST Services Toolkit' - https://github.com/Microsoft/BingMapsRESTToolkit
//
// Just install NuGet package named 'BingMapsRESTToolkit'!
// Don't forget to add namespace BingMapsRESTToolkit to your using block!
//
// Now you can get the coordinates of any address by calling the following method

        public string GetLocation(string address)
        {
            string results = "";
            string key = "Your Bing API key";

            try
            {

                var r = ServiceManager.GetResponseAsync(new GeocodeRequest()
                {
                    BingMapsKey = key,
                    Query = address
                }).GetAwaiter().GetResult();

                if (r != null && r.ResourceSets != null &&
                    r.ResourceSets.Length > 0 &&
                    r.ResourceSets[0].Resources != null &&
                    r.ResourceSets[0].Resources.Length > 0)
                {
                    results = String.Format("Success: {0}:{1}",
                        (r.ResourceSets[0].Resources[0] as Location).Point.Coordinates[0],
                        (r.ResourceSets[0].Resources[0] as Location).Point.Coordinates[1]);

                }
                else
                {
                    results = "No Results Found";
                }

            }
            catch (Exception e)
            {
                results = "Geocoding Error: " + e.Message;
            }
            return results;
        }
