            org =  GetOrganizationSerivice();
           
        }

        #region GetProxy
        public OrganizationServiceProxy GetProxy()

            string strUrl = string.Empty;
            strUrl = "Organization url mscrm online" ;

            Uri organizationUri = new Uri(strUrl);
            Uri homeRealUri = null;
            ClientCredentials credentials = new ClientCredentials();
            credentials.UserName.UserName = "username" ;
            credentials.UserName.Password = "password";
           // credentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
            OrganizationServiceProxy proxyService = new OrganizationServiceProxy(organizationUri, homeRealUri, credentials, null);
            proxyService.EnableProxyTypes();
            return proxyService;
        }

        static IOrganizationService GetOrganizationSerivice()
        {
           
            string strUrl = string.Empty;
            strUrl = "mscrm online";
            ClientCredentials credential = new ClientCredentials();
            credential.UserName.UserName = "user name";
            credential.UserName.Password = "password";
           // credential.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
            OrganizationServiceProxy proxy = new OrganizationServiceProxy(new Uri(strUrl), null, credential, null);
            return proxy as IOrganizationService;
        }
