Subsonic: Using SharedDbConnectionScope together with TransactionScope seems to be broken

问题

Using the code below, the expected behavior is that the database won't reflect the update since ts.Complete() is never called but the updates seems to go through. But if I leave out the SharedDbConnectionScope then the expected behavior is seen. Is there a problem with SharedDbConnectionScope? Btw I am using Subsonic 2.2

using (SharedDbConnectionScope sharedConnectionScope = new SharedDbConnectionScope())           
{
    using (TransactionScope ts = new TransactionScope())
    {                
        // update here
    }
}

Found out the problem. The docs on Subsonic appears to be wrong. If I wrap TransactionScope over SharedDbConnectionScope then it works fine. The right way should be:

using (TransactionScope ts = new TransactionScope())
{
    using (SharedDbConnectionScope sharedConnectionScope = new SharedDbConnectionScope())           
    {
            // update here
    }
}

Edit: As mentioned by firestorm, SharedDbConnectionScope doesn't seem to work in Subsonic 2.2. So the only solution seems to be to install MsDts and don't use SharedDbConnectionScope.

I don't think SharedDbConnectionScope works at all in Subsonic 2.2. The whole idea as far as I can see with the object is that when you use it you don't need to have MsDts installed on the server. I couldn't get this to work at all! When you install MsDts then you don't need SharedDbConnectionScope any more that's why your code works when it gets created after TransactionScope.
