Configuration to Release (Any CPU), I manually had to change the Ouptut from bin\debug...... to bin\release....... which seems weird. But so far so good.\\SomeNAS\Software\AppName as Installer Location.bin\Release\net6.0-windows10.0.19041.0\win10-x64 called AppPackages which contains a AppName_1.0.0.0_Test folder.AppName.msix file from within this AppName_1.0.0.0_Test folder on the NAS device.AppName_1.0.1.0_Test folder to the Installer Location on the NAS device, on next application start there is no installer coming up and prompting to install the new version from the Installer Location.
