The current VS 2005, although looks extremely good and works 70% of the
time, id suggest sticking with VS2003 until at least beta2 comes out.
There will be many changes to VS 2005 as it moves from beta1 to beta2,
and beta2 will also include a go live license which beta1 doesnt (beta1
is for testing purposes only). You can do your basic ground work for
the project in VS 2003 and when beta 2 of 2005 does come out (which may
be soon) it would be easy to just migrate. I would look suggest you
catch up on the changes and enhancements from framework 1.1 to 2.0
though, it will help you in the eventual migration. Bottom line, VS
2005 in beta1 state i wouldnt recomment for any industrial or
enterprise app development. Thats my 2c anyways.
