When I use transactions with sql server I usually do this...
using (TransactionScope scope = new TransactionScope)
{
using (SqlConnection1 = new SqlConnection . . . . .

and this all works great. But now, I need to stretch the transaction across
to sql databases using two different connections i.e.

using (TransactionScope scope = new TransactionScope)
{
using (SqlConnection1 = new SqlConnection . . . . .
{
work
work
}//dispose of connection

using (SqlConnection2, - new SqlConnection . . . . .
{
work
work
}//dispose of connection
scope.Complete();
}//dispose of transaction scope

Is this supposed to work this way? Can a TransactionScope stretch across
many databases and cause a rollback of them all if an exception occurs?

try something like

try
{
using(TransactionScope scope = new TransactionScope())
{
using(conn1 = new SqlConnection(strConnection1))
{
Work1();

using(conn2 = new SqlConnection(strConnection2))
{
Work2();
}
}
scope.Complete();
}
}
catch(TransactionAbortedException ex)
{
ErrorHandler(ex);
}

Hi Gary,

Sure, multiple connections are supported to be joined in the same
TransactionScope. And this is exactly the powerful feature of the new
System.Transactions namespace which help implicitly use MSDTC to perform
distributed transaction. (single connection based transaction can be done
via the ADO.NET 1.1 style ). Here are some articles that also mentioned
this:
