Incident Resolution In CRM Online 2013

[GetLucky]

Нашел более правильное решение, т.к. Case переводиться в состояния закрыто с использованием сущности IncidentResolution, то вполне логично повесить на создание этой сущности плагин, который на Post-operation будет апдейтить Кейс.

public class CaseResolution : IPlugin
    {
        public void Execute(IServiceProvider serviceProvider)
        {
            #region must to have

            IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
 
            // Create service with context of current user
            IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);
 
            //create tracing service
            ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
