At a special event today, Microsoft made its case for why developers should embrace new features in the Windows 10 Fall Creators Update.

“[The] Windows 10 Fall Creators Update provides a developer platform that is designed to inspire the creator in each of us, empowering developers to build applications that change the way people work, play, and interact with devices,” Microsoft corporate vice president Kevin Gallo says. “To truly fulfill this platform promise, I believe that our developer platform needs to be people-centric. Technology should adapt and learn how to work with us.”

To the end, Microsoft has enhanced Windows 10 in the Fall Creators Update with major new features—like the Microsoft Graph, the Fluent Design System, .NET Standard 2.0, and various tooling improvements—that developers can take advantage of in their apps. The firm claims that the Fall Creators Update SDK, or software development kit, literally contains thousands of such improvements.

At a higher level, the Windows 10 Fall Creators Update will introduce consumers to mixed reality—a combination of virtual reality (VR) and HoloLens-like augmented reality (AR)—via new spatial interactions and a coming generation of Windows Mixed Reality headsets. It is the first version to begin including what promises to be a multi-version journey to a new and more modern user experience via the Fluent Design System. And it includes cross-device capabilities via the Microsoft Graph and Project Rome, which together provide an activity feed and task continuation capabilities across PC, and iOS/Android-based phones.

“Whether you’re building immersive experiences for Windows Mixed Reality, games, or business applications, community is crucial to the Windows developer platform,” Mr. Gallo continued. “I’d like to take a moment to thank all developers who are participating Windows Insiders Program and have been using the Fall Creators Update Preview SDK, as well as the partners that joined us on stage today.”

As for the Windows Developer Day event, it’s actually being broadcast in three separate tracks for game developers, commercial software developers, and consumer software developers, respectively. If you’re just learning about this now, you missed it. But I expect Microsoft to make on-demand recordings available soon.
