This is unacceptable and should be fixed ASAP. F# is a mature language existing for more than a decade, there is simply no excuse to let this slide.
Speaking as someone who makes his living writing F# code, I'm as frustrated as anyone about this, but there will be a successful resolution. I just don't know how soon. Before today's announcements my personal thinking was that it would be this autumn. That's still possible. In the meantime I can still function in the F# world, as before. It just remains frustrating to branch out into some of the areas I would like to.
It's actually eye-opening how few the number of people at MS who actually write code is. I suppose if there were more coders they would be stepping all over each other and never get anything done.
