Today, Microsoft announced that its next Connect(); developer event will be held on December 4. As usual, you"ll be able to live-stream the whole thing, including the keynote by Scott Guthrie that will be held at 8:30am Pacific Time.
Last year"s Connect(); event promised over 75 on-demand sessions, but there aren"t any specifics this time around. The website only shows a schedule with the keynote from 8:30 to 10:00, a break from 10:00 to 10:30, a second keynote from Scott Hanselman from 10:30 to 11:30, and live-coding sessions from 11:30 to 5:30pm. And of course, there will be on-demand sessions, but there are no specifics on these.
Everything listed on the page has to do with building apps for Azure. In fact, Windows isn"t even listed once, so don"t get your hopes up for Windows 10 19H1 developer news.
