The process should be the same as for Windows 8.1 (Universal) applications. ( Link )
I used this command:
powershell.exe -ExecutionPolicy Unrestricted -File "c:\program files (x86)\Microsoft SDKs\WindowsPhoneApp\v8.1\Tools\MDILXAPCompile\BuildMDILAPPX.ps1" -appxfilename "C:\SignApps\App.appx" -pfxfilename "c:\SignApps\Certificate.pfx" -password ***** -inputFolder "C:\SignApps\input" -outputfolder "C:\SignApps\output"
The signing process throws this error:
MakeAppx : error: You must include a valid app package manifest file named AppxManifest.xml in the source.
MakeAppx : error: Package creation failed.
MakeAppx : error: 0x80080203 - The specified package format is not valid: The file is not a valid app package because it is missing a required footprint file.
Applications are created through Cordova. When I use the universal Windows 8.1 application, signing works. Using Windows 10, it fails. The application will be provided through mdm (where AET has already been added).
How do I subscribe correctly?
