I pack my Windows application in appx file using Deployment Manager. When I try to upload it to Microsoft Store, it fails with the following message:
"You don't have permissions to specify the following namespaces in the appx manifest file of the package MyApp.appx: restricted namespace: schemas.microsoft.com/appx/manifest/foun...strictedcapabilities "
I try to edit the automatically generated file AppxManifest.xml (removing the "Capabilities" section from it, or completely replacing its contents with a standard pattern from RAD Studio help), change the manifest file name and specify the manifest setting as "Custom". Still, the result is the same: Microsoft Store doesn't like the line about "restricted capabilities", though now this line isn't supposed to be there at all.
It really looks like an appx file always contains a standard, automatically generated manifest, even when I try to specify it in my own way.
