It doesnt support core on windows very well ( all the samples compile for net 4.6) , so it will be some time . Were using 4.6 and most of the new core libs ( logging , configuration , mvc) which provide a lot more benefit to us than switching
compiler / platform. When core is more mature we can simply switch if needed.
