Does .NET Framework 3.5 SP1 require restart

.net-3.5

We have a production machine and are trying to slowly introduce some 3.0 and up features on our web application. 3.5 is installed but I would like to upgrade to SP1, I would just like to know if it requires a restart of the machine in the end so I can schedule some down time.

Thanks!

EDIT: so it did require the restart, thanks guys for the answer…but the hosting company didn't give us the rights to do so…LOL

3.5 SP1 updates 3.0 to SP2 and 2.0 (which contains the CLR) to SP2. If the CLR is loaded in any process the DLLs will not be writable, and a reboot will be required.
