UWP Certification - App Store Signing ( issue - can't sign Store Builds ) - Sideload Builds Sign - no issue

Question

I'm trying to sign an App Store Build. Local ( side loaded builds do sign w/ password ).

A message comes up during build to hit OK / Cancel and to Add new Certificate ( should be there already ) and hitting Ok ( you can enter password and get a missing Criteria/Container error ). If you hit Cancel there isn't a prompt and the Signing Process is cancelled.

Visual Studio 17.7.1 <---- (Updated)

My Certificate store is also getting loaded with Certificates with a GUID as a CN ( 20+ of these ! ).

Also, using the MSIX Tool will NOT Sign with the .CER. Anyone know what the issue is or any fixes ?

Using Token/USB

Thanks !

Tried removing Client Software Tried re-booting OS / IDE Tried Signing with MSIX Tool Tried installing a CERT from my Token.

( once again local builds can and are able to sign - Sideload Build ).

Answer 1

Added Certificate Keeps displaying in Visual Studio for Store Release : ( have USB Key for Signing ).

[ FOR STORE RELEASE - UWP ]

In the .csproj file change this tag below for Project while having .NET Native Compile checked in build properties. ( must have it checked for Store build now - not sure about past ).

( Answering my own question here ).

GenerateTemporaryStoreCertificate to False PropertyGroup.
