Question

我有以下情况。

首先写一些内容到db
在巴士上发送讯息

我想执行像原子操作那样的操作，即在事务中运行它们但在真正分发时无法使它工作。一切都在本地机器上工作，但是一旦服务在另一台机器上就停止了工作。

我的代码看起来像这样：

using(var ts = new TransactionScope())
{
    // Write something to db
    _bus.Send(SomeMessage);
    ts.Complete();
}

我已经做了我能想到的一切并找到了有关的信息，例如在启用了入站和出站的客户端，服务器和数据库上启用DTC，将端口DCOM协议设置为5000-6000。我得到的错误是：

 FailedToSendMessageException: "Failed to send message to address: myserver"

并且堆栈跟踪是：

为什么这不起作用？

在分布式场景中运行时，端点映射需要明确定义接收器队列所在的机器名称。在同一个盒子上运行时，这不是必需的。因此，您的映射不应包含“myserver”，而应包含“myserver @ machinename”。此错误与DTC无关。对于将来的问题，始终包括Nservicebus版本号和传输层
