I'm attending an internal rehearsal of the Windows Presentation Framework PDC talks today and tomorrow.
I just met Nick Kramer after his talk. Nice guy. Check his blog at http://blogs.msdn.com/nickkramer/ if you're interested in WPF Interop story with Win32/MFC/Windows Forms.
And now for something completely different: check Kang Su's blog on Visual C++ at PDC 2005. I whish I could go!
