There were iPhones on the stage here at Build. Big graphics on the screens showed Surface computers lined up side by side with iPhones. Microsoft developer tools are coming for iOS and Android. And Apple’s iTunes is coming to the Windows Store.

The company that once held a mock funeral for the iPhone–complete with dedicated “iPhone trashcans”–now has a very different attitude about the company of Jobs. The Microsoft whose old CEO Steve Ballmer in 2007 famously predicted the iPhone had “no chance; no chance at all” of getting market share, now readily accepts and embraces a world where the iPhone and Android dominate personal computing.

Microsoft talked a lot here at its Build 2017 developer conference about extending Windows experiences over to iOS and Android devices. And it’s not just about fortifying Windows. Microsoft says it not only wants to connect with those foreign operating systems, but by bringing over functionality from Windows 10 (along with content) it hopes to “make those other devices better,” as one Microsoft rep said in a press briefing yesterday.

The developers here at Build cheered when Microsoft announced XAML Standard 1.0, which provides a single markup language to make user interfaces that work on Windows, iOS, and Android. In one demo, the company demonstrated how an enterprise sales app could be extended to an iOS device so someone could continue capturing a potential client’s data on a mobile device. Windows not only sent over the client data that had already been captured, but also the business-app shell that had captured it.

Microsoft has defined the Microsoft Graph as “an intelligent fabric that helps connect dots between people, conversations, projects, and content within the Microsoft cloud.” That definition seems to have shifted a little to include the idea that the graph can be used by developers as a connective tissue to extend Windows experiences to other platforms.

There are many examples in Windows 10. Extending to iOS and Android is a major theme in the features added in the Fall Creators Update coming up, logically enough, this fall.
