MSCRM+ on premise plugin error + could not find default endpoint element that references contract

 Hi All,

If you get error with could not find default endpoint element that references contract

while trying in Plugins or Workflow Activity

Please use below code in your code

BasicHttpBinding myBinding = new BasicHttpBinding();

                myBinding.Name = "BasicHttpBinding_Service";

                myBinding.Security.Mode = BasicHttpSecurityMode.None;

                myBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;

                myBinding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;

                myBinding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;

                // Endpoint Address defining the asmx Service to be called.

                EndpointAddress endPointAddress = new EndpointAddress(@"http://yourwebservice.com/sms_ws/Service.asmx");

                // Call to the Web Service using the Binding and End Point Address.

                SendSMS.ServiceSoapClient myClient = new SendSMS.ServiceSoapClient(myBinding, endPointAddress);
