Was Visual Studio 2008, 2010 or 2012 (v11) written to use multi cores?

Question

Basically i want to know if the visual studio IDE and/or compiler in 2010 and 2012 was written to make use of a multi core environment (i understand we can target m

I think you're probably better off with a higher-clock dual core. I think VS (and most apps today) do not yet take great advantages of multi-threading. VS may have dozens of threads running, but only a subset of operations really take advantage of them well I think. A whole lot of the VS implementation is C++ COM components that run on the STA thread, so the UI thread does the bulk of the work in many scenarios. The fact that many pieces of the VS shell are being rewritten in managed code as part of VS2010 will help break a lot more of these ancient component STA dependencies. As others have mentioned, some key scenarios (like building a large solution) already do take advantage of multiple cores (MSBuild works well in parallel), so if those dominate what you care about, then more cores is better. But for things like IDE UI usage and background compilation, I think most of these are still mostly single-threaded. I've a quad-core box at work, and I rarely see VS2008 use more than 25% of my CPU resources. (I've not used VS2010 enough in earnest to know which scenarios are better, though I know at least a few are better.)
