    Thanks for your reply. That's exactly what I was thinking.

    I think you can create multicore apps in .Net 4.0 but not in 3.5 .

    [EDIT]
    I think you are right in saying the OS decides on which core it runs a thread. So you probaly need a very very intensive operation before it will use the 2nd core. As far as I know, most dual core cpu's these days turn the 2nd core off most of the time to make it more energy efficient.
