WPF-WinForms interoperability functionality (codename "Crossbow") will be in v1 of WPF

This will be of interest to those of you with an investment in Windows Forms. Originally, Microsoft had planned to ship this functionality in the Visual Studio "Orcas" timeframe. However, customers have asked us to release it earlier so that's exactly what we'll be doing now: providing this functionality in the WinFX v1 release itself. This will empower customers to leverage their existing Windows Forms code base (hosting WPF controls in WinForms and vice-versa), and to embrace WPF incrementally without ripping-and-replacing. Mike Henderlight has more details in his blog post [1] and on MSDN TV [2].
