I just witnessed Microsoft trolling preview setup.
Let me set the scene for you. I was in Visual Studio and saw the notifications and I had a minute so I decided to check them and saw there were updates, this one being one of them. I went to update and first it asked me to close all instances of VS. Fair enough, I close VS and continue. Instead of taking a minute at most to install it took ~10 minutes which is insane, but fine, I stopped my work for it... And then I'm greeted by this gem. Restart your computer for freaking .NET core and trolling.. I'm sorry, tooling... Preview... What the actual fuck Microsoft?
