You can now find our patterns & practices Team Development with Visual Studio Team Foundation Server guide on MSDN in HTML. It's the same guidance we hosted on CodePlex. CodePlex was our channel for agile release. Once we baked the guidance, we ported to MSDN. For some customers, MSDN is a trusted source, so being on MSDN is important. Additionally, MSDN provides some additional hooks and channels.
You can still download the Team Development with Visual Studio Team Foundation Server Guide from CodePlex.
