We have just released the WinFX Runtime Components January CTP. This includes a CTP for Orcas, the next release of Visual Studio.
See below for a list of links.
We are also announcing a go-live license for two pieces of WinFX, the Windows Communication Foundation and the Windows Workflow Foundation. This means that customers that need to deploy these pieces live can do so, although of course these products are still in beta. RTM for these, and a go-live for the Windows Presentation Foundation, will come later
