CRM Online IOrganizationService client

In this post I've updated little bit code to connect to Organization Service CRM Online.

    class Program

    {

        static void Main(string[] args)

        {

            String userName;

            String password;

            String organizationUrl;

            userName = <your-live-ID>;

            password = <live-ID-password>;

            organizationUrl = "https://<your-organization-name>.crm.dynamics.com/XRMServices/2011/Organization.svc";

            ClientCredentials credentials = new ClientCredentials();

            credentials.UserName.UserName = userName;

            credentials.UserName.Password = password;

            IServiceManagement<IOrganizationService> orgServiceManagement = ServiceConfigurationFactory.CreateManagement<IOrganizationService>(new Uri(organizationUrl));

            AuthenticationCredentials authCredentials = new AuthenticationCredentials();

            authCredentials.ClientCredentials = credentials;

            authCredentials.SupportingCredentials = new AuthenticationCredentials();

            authCredentials.SupportingCredentials.ClientCredentials = Microsoft.Crm.Services.Utility.DeviceIdManager.LoadOrRegisterDevice();

            AuthenticationCredentials tokenCredentials = orgServiceManagement.Authenticate(authCredentials);

            var organizationTokenResponse = tokenCredentials.SecurityTokenResponse;

            OrganizationServiceProxy _serviceProxy;

            IOrganizationService _service;

            using (_serviceProxy = new OrganizationServiceProxy(orgServiceManagement, organizationTokenResponse))

            {

                _service = (IOrganizationService)_serviceProxy;

                WhoAmIResponse response = (WhoAmIResponse)_service.Execute(new WhoAmIRequest());

                Console.WriteLine(response.UserId.ToString());

            }

            Console.ReadLine();

        }

    }
