            base.RegisteredEvents.Add(new Tuple<int, string, string, Action<LocalPluginContext>>(20, "Create", "incident", new Action<LocalPluginContext>(ExecutePreCaseCreate)));

            var service = localContext.OrganizationService;
            var context = new OrganizationServiceContext(service);

            // Get Organization Business Closure Calendar Id
            var organization = service.Retrieve("organization", context.OrganizationId, new ColumnSet("businessclosurecalendarid"));

            var query = new QueryExpression("calendar")
            {
                ColumnSet = new ColumnSet(true),
                Criteria = new FilterExpression()
            };

            // Add condition to get Get Calander where CalanderId is equal to Organization's businessclosurecalendarid
            query.Criteria.AddCondition(new ConditionExpression("calendarid", ConditionOperator.Equal, organization["businessclosurecalendarid"].ToString()));

            // Get Calendar
            var businessClosureCalendar = service.RetrieveMultiple(query).Entities[0];

            // Get the Calendar rules
            IEnumerable<Entity> calanderRules = businessClosureCalendar != null ? businessClosureCalendar.GetAttributeValue<EntityCollection>("calendarrules").Entities : null;
        }
    }
}
