看一下这篇文章,这是对 Mariani 的采访,关于是否有必要提供64bit VS 的。Mariani 最后说
I know there are customers that would benefit from a 64 bit version but I actually think that amount of effort would be better spent in reducing the memory footprint of the IDE’s existing structures rather than doing a port. There are many tradeoffs here and the opportunity cost of the port is high.
也就是说VS的开发团队知道64bit 的VS 将使很多用户受益,但他们还有更重要的事情要做,比如降低VS的内存占用等,作为折中,他们暂时不打算开发64bit 的VS
