What is the advantage of using Visual Studio 2008 on Xp 64bit

Currently my development environment is Windows Xp 32 bit and Visual studio 2008 with 开发者_运维问答SP1.

I have 2 GB of RAM and C2D 2.4 GHz processor.

What are the advantages if i install Xp 64 bit?? Whereas the application which i am developing is intended to run on Xp 64 bit machine with 32GB of memory

There will be no advantage except that your development OS would then be the same as the target production OS. This may aid in testing/debugging on your own machine (assuming that is what you do.)

In general the advantages of a 64 bit OS are mainly the ability to address more RAM, but your machine only have 2GB anyway.
I suppose you would also get IIS 6.0 rather than 5.1 as in XP32, if that matters. However, XP 64 bit is not very highly regarded at all.
