x86 only metro application

Question

I have a legacy x86 C/C++ library and I am planning to use it in my app. No, I don't have the source anymore so I can't compiled it for ARM.

Can I publish the app and make it only available to x86/x64 win8 users? Does Windows MarketPlace allow such app?

Answer 1

Older C-runtimes may use API which aren't allowed for Metro style apps, so you'll want to make sure that your app using the library can pass the Windows App Cert Kit.

Your question about whether ARM builds are required for the Store would be better asked in the Store forum. I'll move this for you. You can also look at the Certification requirements for Windows apps documentation. The only requirement that I see that mentions processor type is 3.3:

3.3 Your app must provide the same user experience on all processor types

If your app has a different user interface or functionality when it runs on different processor types, you must submit a separate app for each processor type and describe the differences in the Description of each app.

Thanks. The requirement is related but not crystal clear on if completely missing a processor type is OK. I haven't tried to submit any app yet - can someone please tell me if you can submit app for just one processor type?

Hi yiyiyaya,

You are able to submit for either or select both processers. 

Thanks-

Thanks, this help me. 

Answer 5

Can I submit version 1.0 of the app as x86 only and on 2.0 change the processor to both x86 and ARM?
