Dynamics Community Forum Thread Details

Hi all,

I'm currently developing on CRM 2013 on-premise and have been trying to develop a plug in that will ultimately send CRM data to an external system via their web service.

I have created a plugin and added a method that logs into the service which is called from ExecutePostContactUpdate. When I registered the plugin in the Sandbox the plugin errored out with the following:

<ErrorDetails xmlns:d2p1="schemas.datacontract.org/.../System.Collections.Generic" />
<Message>System.Security.SecurityException: Microsoft Dynamics CRM has experienced an error. Reference number for administrators or support: #904A5CD2</Message>

When I then select an Isolation mode of None I get the following which, while a slight improvement is still not working:

Unhandled Exception: System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=6.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: There was no endpoint listening at xxx.com/.../basic that could accept the message.

I know that the code works as I have tested it in a separate console app and I can connect without issue.

The code in the plugin is as follows:

        protected void ExecutePostContactUpdate(LocalPluginContext localContext)
        {
            if (localContext == null)
            {
                throw new ArgumentNullException("localContext");
            }

            // TODO: Implement your custom Plug-in business logic.
            IPluginExecutionContext context = localContext.PluginExecutionContext;
            IOrganizationService service = localContext.OrganizationService;


            if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
            {
                Entity entity = (Entity)context.InputParameters["Target"];

                if (entity.LogicalName == "contact")
                {
                    string loginTest = ivpLogin();
                    throw new InvalidPluginExecutionException(loginTest);
                }
            }
        }

        private string ivpLogin()
        {
            BasicHttpBinding binding = new BasicHttpBinding();
            binding.Name = "BasicHttpBinding_ExternalWebService";

            binding.CloseTimeout = System.TimeSpan.Parse("00:01:00");
            binding.OpenTimeout = System.TimeSpan.Parse("00:01:00");
            binding.ReceiveTimeout = System.TimeSpan.Parse("00:01:00");
            binding.SendTimeout = System.TimeSpan.Parse("00:01:00");

            binding.AllowCookies = false;
            binding.BypassProxyOnLocal = false;
            binding.HostNameComparisonMode = System.ServiceModel.HostNameComparisonMode.StrongWildcard;

            binding.MaxBufferSize = 65536;
            binding.MaxBufferPoolSize = 524288;

            binding.MessageEncoding = System.ServiceModel.WSMessageEncoding.Text;
            binding.TextEncoding = System.Text.Encoding.UTF8;
            binding.TransferMode = System.ServiceModel.TransferMode.Buffered;

            binding.UseDefaultWebProxy = true;
            binding.ReaderQuotas.MaxDepth = 32;
            binding.ReaderQuotas.MaxStringContentLength = 8192;

            binding.ReaderQuotas.MaxArrayLength = 16384;
            binding.ReaderQuotas.MaxBytesPerRead = 4096;
            binding.ReaderQuotas.MaxNameTableCharCount = 16384;

            binding.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.Transport;
            binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.None;
            binding.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;

            binding.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;
            binding.Security.Message.AlgorithmSuite = System.ServiceModel.Security.SecurityAlgorithmSuite.Default;

            EndpointAddress endpoint = new EndpointAddress("xxx.com/.../basic");

            client = new ExternalWebServiceClient(binding, endpoint);

            requestInfo = new RMLoginRequestInfo();
            requestInfo.DeviceKey = Guid.NewGuid().ToString();
            requestInfo.UserName = _userName;
            requestInfo.Password = _passWord;
            loginResponse = client.Login(requestInfo);

            if (loginResponse.IsSuccess)
            {
                return "true";
            }
            else
            {
                return "false";
            }

Many Thanks for any help given!
