Plus, .NET Core is the first developed openly on GitHub as open source, so you get the teething pains of seeing how all the sausage is made. On the one hand this is great to see so much transparency and open source collaboration. On the other hand, for a lot of .NET veterans used to only hearing about .NET updates maybe once every three years at a well rehearsed developer conference, the world of open source transparency is definitely a fire hose of information updates and that makes for a very rough transition.
