With all of the WinFx Beta 2 goodness now released the obvious question is whether there is a go-live license with this Beta, as we have not had an updated go-live release for Indigo or WF since the Jan CTP.
Unlike the Jan CTP, which was only go-live for Indigo and WF, this release is a go-live release for all three technologies (WCF, WPF, and WF). More info here
