Is the Visual Studio Application 32Bit , and thus can only address max 4GB ram?

Yes, Visual Studio is 32bit. To produce 64-bit code of your program it uses cross compiler (but there is already Beta 2 version of 64-bit tools).
It could use 3Gb of virtual memory on 32-bit OS (when OS loaded with increaseuserva
switch or /3GB
switch on WinXP), and 4Gb of virtual memory on 64-bit OS. It was built with LARGEADDRESSAWARE
flag. You could check it by using dumpbin utility with /HEADERS
switch. To get more information on virtual memory limits you could read this article by Mark Russinovich.
As said above, Visual studio is 32-bit application. That's why IDE can use only 2BG of virtual memory. But exists solution that allows your VS use more memory. In this article explains how you can do that.

2VS already built with LARGEADDRESSAWARE. No need to edit it. Sep 3, 2009 at 10:33

This would have possibly been a concern on VS 2005 or even 2003, but the question is for VS2008 Sep 3, 2009 at 11:28

Actually running under 64 bit operating systems 32 bit applications can now address up to 4 GB.– JustinNov 1, 2009 at 20:18
