Description

Project
MSIX SDK (MakeAppx.exe)

Describe the bug
I am unable to sign a WinUI application as my code signing certificate has ST in the subject which is not permitted in the Publisher element in the AppxManifest.xml

To Reproduce
Create a new WinUI application and sign the app package with a code signing certificate which has a subject containing ST

Expected behavior
The AppxManifest.xml would allow ST in the publisher

Research direction

Reproduce the signing failure with MakeAppx.exe using a certificate whose subject contains ST, and inspect how the Publisher value is derived for AppxManifest.xml. Done means a WinUI application package can be signed and its manifest publisher permits the certificate subject containing ST.
