Should I use TransactionScop e?

hardieca

Hi,

I'd really like to use TransactionScop e within the Business Layer of
my web application. A book I'm reading makes a note that it should not
be used in a shared web hosting environment because the server may get
re-configured. Can anyone elaborate on this?

Regards,

Chris

Chris,

I don't see how the server becoming reconfigured affects the use of
TransactionScop e.

You want to use the TransactionScop e class when you want the code
encapsulated in the scope of the instance (it's meant to be used in a using
statement) is to run in a transactional context.

Look at the documentation for the TransactionScop e class on how to use
it.

Hope this helps.

TransactionScop e.

Maybe if DTC is disabled... but by that note, virtually everything is
a contender... almost *any* configuration change could potentially
break something... all our code will always be at the mercy of the
services that the OS and runtime provide

services that the OS and runtime provide

Actually, TransactionScop e is supposed to work even if DTC is
disabled/uninstalled, as long as you don't do anything that causes
promotion. I've actually got an open bug report on Connect about this (i.e.
it failed for me when DTC wasn't installed), but I've been communicating
with a tester at MSFT who's working on the bug and he can't get it to
reproduce. Indeed, when I tried to repro it myself, I couldn't do it
either - as long as the transaction doesn't need to be promoted, DTC should
not be required.

Correct; but the OP didn't specify an RDBMS; only MS SqlServer 2005
supports promotable transactions; prior to this you will get DTC
immediately, without promotions even being an issue.
