Microsofthas announced a new mechanism to help developers to buildWindows 11apps for Arm-based hardware, as it counts down to the next major Windows release.
The announcement expands Microsoft’s seemingly aggressive push forWindows 11onArm. The software giant has already announced the availability of native 64-bit Arm versions of its marquee apps, such asOffice.
To continue that momentum, Microsoft has unveiled ARM64EC (“Emulation Compatible”) to help developers get their apps to run on Arm without incurring any performance penalties.
“With the latestVisual Studiotools in preview and the Windows 11 Insider SDK, you’ll be able to take advantage of ARM64EC to incrementally transition your app to running with native speed on ARM, even if you have dependencies or plugins that don’t support ARM yet,” wrote Marc Sweetgall, Senior Program Manager at Microsoft,in a blog post.
Interoperable apps
Historically, supporting a new architecture meant developers had to spend considerable time and effort porting their app. However, ARM64EC gives developers the option to identify critical portions of the app that will benefit from native performance and rebuild just these instead of the entire app.
Thanks to ARM64EC interoperability with x64, the application binary interface (ABI) will make sure that any ARM64EC code in the app runs natively, while any x64 code will run with the help of Windows 11 on Arm’s built-in emulation.
This interoperability gives developers the time they need to recompile other components of the app to run natively on 64-bit Arm.

Sweetgall adds that Microsoft is using ARM64EC in the Windows 11 Arm port of Office, to ensure that the existing x64 plugins continue to work on Arm without any issues.
