may make use of more RAM than a 32-bit one. Whether it is designed to do so is another question. To avoid having 2 separate code bases the 64-bit version may just be a straight recompile of the 32-bit one.

OK, just to understand - if I have a 32 bit OS anything over 3gb is wasted , correct?
But if I have a 64 bit OS what you have said above applies ( with Craig's post implying that VS the same in 32 or 64 )
As to SQL server, am I correct that it is optimized for 64 bit if you run 64bit on Win7 64 (or does that only matter in mult-processer scenarios etc?)

Half the harm that is done in this world is due to people who want to feel important. They don't mean to do harm-- but the harm does not interest them. Or they do not see it, or they justify it because they are absorbed in the endless struggle to think well of themselves.

Democracy is two wolves and a sheep voting on what to have for lunch.
Liberty is a well-armed sheep contesting the vote.
