Handling application updates with App Installer and MSIX in Windows 10 19H1

Matteo Pagani 

Hi Matteo,

I would like to be able to install my package offline using .appinstaller, i can do that by just changing the URI to a local path works fine.

I also have the .appinstaller on the server so that i can download he updates and update the app which works casue i speficy the URL for download

but the problem is for checking if the update is actually available, cause this code

var pm = new PackageManager();
Package currentPackage = pm.FindPackageForUser(string.Empty, Package.Current.Id.FullName);

PackageUpdateAvailabilityResult result = await currentPackage.CheckUpdateAvailabilityAsync();

does not take any URI  so how would i go about that ?

Please note that the .appinstaller file get's deleted after the installation but i guess windows is storing it's file location somewhere cause otherwise how does the currentPackage  know where to look for the file, if you remove the .appinstaller it will cause an error while checking for the update.

Thanks,

Karol
