Visual Studio 2010 will be 32-bit exclusive 'No 64-bit'

Microsoft won't follow the example set with Office 2010 with the next iteration of its development platform and tools, when it comes down to providing a 64-bit flavor of Visual Studio 2010 (download). Well, there’e several concerns: “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).[…] 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,” stated Mariani.
