You can run live applications on WinFX today - but not the February CTP

I previously blogged on the go-live license for the January CTP. Many folks have asked me if the same applies to the February CTP. The answer is no. Additional testing went into WCF and WF for January to get them to a Beta 2 level. This is not true for the February CTP. We may do another CTP before RTM which has a go-live license - but for now you will need to stick with the January CTP if you plan to use these technologies in a live environment.
