Not disappointed or surprised at all. Microsoft routinely promote new frameworks promising the world, and then drop it years later after the faithful have spent $ millions investing in the new platform. I still remember Microsoft trying to convince the world to rewrite billions of lies of C++ in C#. And then after a number of years suddenly doing a 180 and making C++ high priority again. I highly recommend ignoring pretty much everything Microsoft hypes and instead look at what is still working well and being supported 10 years after it was introduced.
