Implementing transactions over multiple databases

Question

I am performing data changes on multiple databases, and I want to implement a transaction that will cover all of the changes.

This is what I currently have:

Answer 1

Use the TransactionScope class like this:

using (TransactionScope ts = new TransactionScope())
{
    //all db code here

    // if an error occurs jump out of the using block and it will dispose and rollback

    ts.Complete();
}

The TransactionScope class will automatically convert to a distributed transaction if necessary.
