Microsoft confirmed today that its online-only Build developer conference will run between May 25th and May 27th, though there’s still no word on when registration will open. (If last year is any indication, our money is on “the end of April.”) “Microsoft Build is where developers, architects, start-ups, and students learn, connect, and code together, sharing knowledge and expanding their skillset, while exploring new ways of innovating for tomorrow,” the company’s events page explains.
