    public static Incident GetCase(XrmServiceContext context, Guid IncidentID)

           {

               try

               {

                   var incidentQuery = from incident in context.IncidentSet

                                       where

                                           incident.Id == IncidentID

                                       select incident;

                   if (incidentQuery.ToList().FirstOrDefault() != null && incidentQuery.ToList().Count > 0)

                   {

                       return incidentQuery.ToList().FirstOrDefault();

                   }

                   return null;

               }

               catch (FaultException<OrganizationServiceFault> ex)

               {

                   throw new InvalidPluginExecutionException("Detail Message:" + ex.Detail.Message + "\nError Details:" + ex.Detail.ErrorDetails + "\nMethod Name:" + "GetCase");

               }

           }

    and error is :

    I think the error is somewhere else in your code. The error indicates that there has already been a communication error. This will be a property related to the XrmServiceContext, so I expect the problem is either how you instantiate this in the calling code, or with some other use of this object

    Use service.retrieve request to fetch incident details instead of using organizationservicecontext.
