跨应用程序域和进程的TransactionScope [英] TransactionScope across AppDomains and processes

问题描述

这是真的使用System.Transactions的（主要的TransactionScope）在不同的应用程序域和进程？

Is it real to use System.Transactions (primarily TransactionScope) across different AppDomains and processes?

DependentTransaction 只有内的一个AppDomain中的作品。

DependentTransaction works only inside one AppDomain.

推荐答案

是的，它的工作原理。我们通过WCF流​​动的事务，呼叫的过程中事务处理COM +组件，并手工传递交易从.net 2.0 ASMX Web服务的WCF服务。

Yes, it works. We are flowing transactions via WCF, calling out of process transactional COM+ components, and manually passing transactions from a .NET 2.0 asmx web service to a WCF service.

现在，是不是说，设置不挑剔。我想大多数的问题都围绕得到MSDTC正确设置所有服务器上。

Now that is not to say that the setup is not finicky. I think most of the issues were around getting MSDTC set up properly on all the servers.

更新

我们不使用 DependentClone 。我们使用 GetTransactionFromTransmitterPropagationToken 通过交易作为字节数组。非常相似的第二示例<一href="http://blogs.microsoft.co.il/blogs/sasha/archive/2010/04/30/propagating-a-transaction-across-appdomains.aspx"相对=nofollow>传播在整个应用程序域的交易。

We don't use DependentClone. We are passing the transaction as a byte array using GetTransactionFromTransmitterPropagationToken. Very similar to the second example of Propagating a Transaction Across AppDomains.

作为一个例子：

客户端：

public void CallOutOfProcessAndPassTransaction
{
    Client client = new Client();

    client.DoSomethingTransactional(
        System.Transactions.TransactionInterop.GetTransmitterPropagationToken(
            System.Transactions.Transaction.Current)
    );
}

服务：

public void DoSomethingTransactional(byte[] tx)
{
    using (TransactionScope ts = new TransactionScope(
               TransactionInterop.GetTransactionFromTransmitterPropagationToken(tx)))
    {
        // Do Something

        // vote to commit the transaction if the caller also agrees
        ts.Complete();
    }
}
