Question

我有下一个代码：

class ProcessHandler : IHandleMessages<StartProcess>
{
    public IBus Bus { get; set; }

    public void Handle(StartProcess message)
    {
        //some long living process (over 3 min)

        Bus.SendLocal(new SameMessage()); //get error here
    }
}

错误消息：该操作对事务状态无效。

有人可以帮我这个吗？感谢

Nsb处理程序被system.transactionscope包围。您可以在system.transaction-section中更改app.config中的默认超时。 Nsb fluent配置中有一个事务设置; Configure.Transactions.Advanced，也可能有超时设置。

maxtimeout是10分钟，如果你正在进行操作，你必须在machine.config中更改它（必须在启动任务上执行此操作）。

尝试在Handler中创建Bus.SendLocal时，该操作对于事务的状态无效（本地Azure工作者）
