Standalone Team Foundation Server 2010 API Installer
If you are or want to develop applications against Microsoft’s Team Foundation Server, you and your target audience had to have at least the Team Explorer edition of Visual Studio installed, which still comes at a size of ~200mb.
Howerver, as of a couple days ago, Microsoft also offers a lean API (Client Object Model as it’s called in Tfs lingo) installer that works without any Visual Studio edition installed and weighs only 6mb.
It’s for 2010 Sp1 as of speaking, but they announced a 2012 version of it will be available together with / on the day Visual Studio 2012 is released. Enjoy
