Yesterday Microsoft released the June CTP of the newly renamed .NET Framework 3.0 which was previously known by the codename WinFX. You can download this CTP here:.NET Framework 3.0 June CTP
Interestingly, this download page mentions that this CTP is intended only for users of Windows Vista Build 5456, Windows XP, or Windows 2003 Server. Those of you with a keen eye will notice that Windows Vista Beta 2 was build 5384, meaning that Microsoft must be about to release build 5456 to beta testers although it is unclear if this build will also be made available to MSDN subscribers. I would hope that it would be made widely available to MSDN subscribers so that they too can contribute to the quality, not only of Windows Vista, but of the .NET Framework 3.0 as it progresses towards the RTM milestone. If you install this CTP and have any suggestions or bugs to report I would advise you to surf on over to the Microsoft Product Feedback Center and log them there for Microsoft to triage and hopefully act upon accordingly. The Microsoft Product Feedback Center is now hosted on the Microsoft Connect website which has recently undergone a major revision.
In addition to the CTP build of the .NET Framework 3.0, a release candidate (RC) build of the Windows Workflow Foundation has also been released and can be downloaded here:
