We've just published the February CTP of the WinFX Runtime Components. This is a big step forward for Windows Presentation Foundation in particular, with several months of development work being exposed for the first time. (Those of you with eagle eyes will have noticed that the January 2006 release was identical to the December 2005 release, which in turn only had a couple of minor bug-fixes compared to the November 2005 release.)
This release demonstrates a number of major performance improvements for WPF applications compared previous releases. We're now API complete for the final release (i.e. there are no more features to be added in, there shouldn't be any more major breaking changes between now and RTM.) If you've only been hovering on the sidelines of WPF, now is a perfect time to come and join the party!
I'll post a separate entry outlining some of the major breaking changes since the last CTP, but for now I want to provide the links:
(The files take a little while to propagate to all the download servers, so allow an hour or so for them to go live if you're experiencing "File Not Found" errors.)
Expect to see a matching update to Expression Interactive Designer soon. (Each version is tied to a specific WinFX release, so the current version doesn't work with the Feb CTP.)
