我创建了一个将成员插入营销列表的工作流。但是当这个过程完成时，我注意到营销列表成员计数器总是 = N -1

                    RemoveMemberRequest.EntityId = Contact.Get<EntityReference>(executionContext).Id;                   
                    RemoveMemberListResponse RemoveMemberResponse = service.Execute(RemoveMemberRequest) as RemoveMemberListResponse;
                    log.addLogs(ref _logs, "Remove from  marketing List - Fine"); 

                }
                else
                {
                    log.addLogs(ref _logs, Inserimento.Get(executionContext) == true ? "L'utente è già presente nella Lista di Marketing." + _separatore : "L'utente non è presente nella Lista di Marketing." + _separatore); 
                }

                log.WriteLog( _logs);
                var MyList = (from l in datacontext.ListSet where l.Id == listId.Id select l).ToList().FirstOrDefault();
                service.Update(MyList); 

            }
            catch(Exception ex)
            {
                if (log == null)               
                    new Log_Entity(service).WriteLog( _logs, ex.Message); 
                else                
                    log.WriteLog( _logs, ex.Message);               
            } 

        }

    }
}

在我的日志中，每次我调用 Service.Update() 时，我都会发现以下消息：

EntityState 必须设置为 null、Created（对于 Create 消息）或 Changed（对于 Update 消息）

在操作后注册插件（或者甚至异步，如果你觉得合适的话）。
