How to detect if a UWP/Iot Core application is being run on an ARM processor or a desktop processor (x86/x64)? Alternatively, is there any other way to detect if the application is run on desktop Windows or on a device? It would also help to detect if the application was launched in Visual Studio or not.

I already tried the Windows.Security.ExchangeActiveSyncProvisioning.EasClientDeviceInformation class but it does not provide this information.

Googling has not taken me further.

    I haven't done nearly as much UWP development as I should have. I think this looks about right: suchan.cz/2015/08/uwp-quick-tip-getting-device-os-and-app-info . Could you take a quick look and confirm whether it's what you're after (specifically Package.Current.Id.Architecture.ToString())? – goobering Oct 14 '16 at 12:24
  • @goobering : thank you! You should have written that as an answer as it completely solved my problem! – Petri K Oct 14 '16 at 13:21
  • Note that this probably isn't as reliable as you want--some full-sized computers run ARM (Chromebooks, apparently some forthcoming blade servers), and Android can run on Atom. – chrylis -on strike- Oct 14 '16 at 21:59
  • @chrylis : thank you for the comment! In our case, we actually implemented the functionality with the OS family information also provided by the Package class (as suggested in the answer of @goobering). This is not about anything going to production, it is just to ease things to university students programming our device. – Petri K Oct 16 '16 at 10:26

This article on suchan.cz describes how to access several system details in a UWP application:

  • current OS family - phone/desktop/...
  • current OS build number - 10.0.10240.16413
  • current OS architecture - x86/x64/ARM
  • current App Display Name - Battery Tile for instance
  • current App Version - 3.0.2.0
  • current Device manufacturer - Nokia
  • current Device model - Lumia 1520

Specifically, the code used to access the system architecture is:

// get the package architecure
    Package package = Package.Current;
    string systemArchitecture = package.Id.Architecture.ToString();
  • Package is in namespace Windows.ApplicationModel – erict Oct 31 at 19:26
