alt Hacker NewsBorland was pretty good on the GUI front, I think we're forgetting how easy it was to get something rolling in Delphi. It's baffling Microsoft still hasn't gotten their stuff together on this. They've been just releasing new frameworks since the WinRT era and hoping something sticks.
Microsoft's GUI problem is two-fold.
Firstly, that nobody believes them when they swear that {new GUI framework} will be the future and used for everything. Really. Because this time is not like those other times.
Secondly, pre-release user feedback. Ironic, given other parts of Microsoft do feedback well.
Imho, the only way MS is going to truly displace WinForms at this point is to launch a 5-year project, developed in the open, and guided in part by their community instead of internally.
And toss a sweetener in, like free app signing or something.
