Question

我见过其他类似问题，但我还没有找到合适的解决方案。

我在调用Database和ServiceBus时使用了一个事务。

我正在为我的数据库使用UnitOfWork / EntityFramework。

这是我的代码

/*Creating the list and adding to UnitOfWork repository*/
....
using (TransactionScope scope = new TransactionScope())
        {
            _unitOfWork.Save();
            ExportGroups(myGroupList);
            scope.Complete();
        }

这是ExportGroups函数的片段

public void ExportGroups(IEnumerable<Group> groups)
{
     /*Generating BrokeredMessage message*/
     Task.Factory.StartNew(() =>
        {
            MessagingFactory factory = CreateMessagingFactory(...);
            if (factory != null)
            {
                var sender = factory.CreateMessageSender(topicName);
                sender.Send(message);
            }
        }).Wait();

}

这在我的开发环境中没有任何问题。但是当我们投入生产时，我得到以下错误

＆＃34; System.InvalidOperationException：其他资源管理器/ DTC不支持本地事务。＆＃34;

在机器上启用了DTC，我们使用它来处理其他交易就好了，但它们都没有使用ServiceBus。

Answer 1

不同的Windows Azure服务不支持事务。也就是说有很多ways to send messages to service bus with transactional guarantees。

HTH！ SREE

Answer 2

using (TransactionScope scope = new TransactionScope()
{
    //Database call

    using (var transaction = new TransactionScope(TransactionScopeOption.RequiresNew, TransactionScopeAsyncFlowOption.Enabled))
    {
        sender.Send(message);
        transaction.Complete();
    }
}

生产环境中的transactionScope和ServiceBus存在问题
