In addition to what others mentioned, COM+/MTS transactions are extremely
useful if you want to have one component make calls to other components and
have it all within a single transaction. Doing this yourself with SQL
transactions would mean passing around a Connection object and keeping track
of everything yourself. Why not let the COM+ runtime do this for you.
If you have simple components where each transaction is fully contained in a
single object method, you can probably get by with just SQL Server
transactions. Once things get more complex it just makes sense to take
advantage of the COM+ services.
