The February CTP is finally available for download, along with sync’d versions of the rest of the WinFX experience:  the Windows SDK, the “Orcas” CTP for Development Tools for WinFX (a role that used to be fulfilled by Visual Studio Extensions for WinFX), Visual Studio Extensions for Workflow, and of course the readme.  I’ve been looking forward to this release because it contains almost all of the last changes I’m expecting to the product—from here on in, I’m just hoping for more more more stabilization.  There’s one mainline change here—a keyword change in config;  most of the other changes are to improve general usability, interoperability, and security.  Ed Pinto has created a breaking changes document that specifies everything you might need to consider when bringing code forward from the Jan to Feb CTP.  Enjoy!
