App Installer file APIs
The PackageManager and Package classes in the Windows SDK provide methods you can use to add or modify packages via App Installer files, or to retrieve information about apps with an App Installer association.
| Method | Description | Minimum supported release |
|---|---|---|
| PackageManager.AddPackageByAppInstallerFileAsync | Allows single or multiple app packages to be installed with an .appinstaller file. | Windows 10 Fall Creators Update (version 1709, build 16299) |
| PackageManager.RequestAddPackageByAppInstallerFileAsync | Allows single or multiple app packages to be installed with an .appinstaller file. | Windows 10 Fall Creators Update (version 1709, build 16299) |
| Package.GetAppInstallerInfo | Returns the .appinstaller xml file location. This allows app developers to retrieve the .appinstaller xml file location when needed by their app. | Windows 10, version 1809 (build 17763) |
| Package.CheckUpdateAvailabilityAsync | Checks for updates to the main app package listed in the .appinstaller file. It allows the developer to determine if the updates are required due to .appinstaller policy. This method currently only works for applications installed via .appinstaller files. | Windows 10, version 1809 (build 17763) |
