c# - 是否可以在不允许升级到 DTC 的情况下将 .NET 的 TransactionScope 与 Sql Server 2005 一起使用？

Question

我正在处理屁股服务器中的一些非常痛苦的事情，我希望他们只使用没有 DTC 的事务(现在这样我可以专注于其他地方)。我在范围内使用多个数据库，所以典型的行为是促进，但我想避免它。如果可能的话，在此模型下，不确定交易的行为是什么？我假设 tx.Complete() 会抛出？

这是因为我得到了这些随机错误(如果你能提供帮助，请随意插话为什么会这样 - 这些是零星的，不是恒定的):

不幸的是，我不认为在涉及多个数据库时避免将事务提升为 DTC 事务是不可能的，甚至是使用多个连接对象的单个数据库。
