SWEET! Scott Hanselman has a post on his blog showing you how to get MSBuild to build in Parallel. this could come in very handy. we have a machine here for building our projects on, and you could be talking 4 or 5 projects, if not more, all linked together. to enable parallel builds on them, it would speed up the build big time… especially concidering there are 2 quad core procs in this box! :)
