        static void Button1_Click()
        {
            ClientCredentials Credentials = new ClientCredentials();
            Credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;
            //This URL needs to be updated to match the servername and Organization for the environment.
            Uri OrganizationUri = new Uri("http://crmserver:5555/crm2011dev/XRMServices/2011/Organization.svc");
            Uri HomeRealmUri = null;
            using (Microsoft.Xrm.Sdk.Client.OrganizationServiceProxy serviceProxy = new Microsoft.Xrm.Sdk.Client.OrganizationServiceProxy(OrganizationUri, HomeRealmUri, Credentials, null))
            {
                serviceProxy.ServiceConfiguration.CurrentServiceEndpoint.Behaviors.Add(new ProxyTypesBehavior());
                IOrganizationService service = (IOrganizationService)serviceProxy;
                //fetch example
                string opportunity_count = @"<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>
                                              <entity name='contact'>
                                                <attribute name='fullname' />
                                                <attribute name='new_customernumber' />

                                            </fetch>";
                EntityCollection contact_count_result = service.RetrieveMultiple(new Microsoft.Xrm.Sdk.Query.FetchExpression(opportunity_count));
                //Create loop of the result                 foreach (var c in contact_count_result.Entities){}
                //end fetch example
                Console.ReadKey();
                //This code will clear the textboxes after the contact is created.
            }
        }
    }
