This! 100%! For many many years now. It's painful for all people involved (including the .NET community). Microsoft doesn't mind though, they love developing a shitload of competing frameworks, because once a framework hits version 3 or 4 where it starts to feel slightly mature then the internal incentives require the teams to dump the project and "invent" something new to stay relevant internally.
