ARM64 for Windows Store

[mifi]

Windows Store (appx) seems to support arm64.

Yep,

From what I've read if you go to Partner Center, create a new submission for your existing app, and upload both your existing package(s) + the new ARM64 package together. The Store handles the rest, it will automatically serve the right architecture to the right device.

If your previously published submission used a bundle (.appxbundle), a previous submission released with a .appxbundle means subsequent submissions must continue to contain a .appxbundle. Microsoft Learn In that case, you'd need to bundle both your x64 and ARM64 .appx files together into an .appxbundle using MakeAppx.exe rather than uploading them as separate files.

From a user perspective when I view an app in the Store (using the Microsoft Store app, not the website) on my Windows ARM device and expand the "System Requirements" section, if "Arm64" is listed under the "Architecture:" label then there's a native version available.

Thanks for the info. I will try this now. First without an appxbundle because it seems to be not needed yet then.
