Click-Once is like... the smartest idea that ever got built by people who have never worked in places that need something like Click-Once.

I am of the opinion that if they had dropped the "use apps over the web" angle and focused on small-medium-enterprise continuous deployment they woulda had a true game changer on their hands... Click-Once dovetails naturally into something like Apples launchpad, its "turn it off and turn it on again" workflow was ideal for 'Sue in Accounting', its simplified publishing model is great for ISVs with lots of customers, and its sandboxy requirements are a natural fit for the way dotnet core is coming together.

And, yeah, that the Windows ecosystem is still worseoff than apt-get forever ago is a) shocking, b) further proof that Richard Stallman was right about everything ;)
