I know that in visual studio 2010 there wasn't 64 bit version. Is there 64 bit version for vs2012?

回答1:

No, there isn't.

Probably for the same reasons stated for Visual Studio 2010 (no need for the additional address space, and because for this application it would bloat it, slow it down and will take much too long to port to such an architecture, not to mention - the 32bit version works on 64bit machines).

回答2:

No there is no 64 bit version.

You can check out this link (Thought to add the reason why it is not added)

why not 64 bit right away?

First, from a performance perspective the pointers get larger, so data structures get larger, and the processor cache stays the same size. That basically results in a raw speed hit (your mileage may vary). So you start in a hole and you have to dig yourself out of that hole by using the extra memory above 4G to your advantage. In Visual Studio this can happen in some large solutions but I think a preferable thing to do is to just use less memory in the first place. Many of VS’s algorithms are amenable to this.

Secondly, from a cost perspective, probably the shortest path to porting Visual Studio to 64 bit is to port most of it to managed code incrementally and then port the rest. The cost of a full port of that much native code is going to be quite high and of course all known extensions would break and we’d basically have to create a 64 bit ecosystem pretty much like you do for drivers.

No. There are apparently no plans also.
