Remarks
To get the list of packages that have updates available, use the GetAppAndOptionalStorePackageUpdatesAsync method. After you download the packages, you can install them by using the RequestDownloadAndInstallStorePackageUpdatesAsync method. For more information about using this method, including a code example, see Download and install package updates for your app.
This operation will not block. The IAsyncOperationWithProgress object returned by this method will complete after the update packages are downloaded.
When you call this method, the OS displays a dialog that tells the user that an app update is available to download and asks the user's permission to proceed with the download. If the user does not grant permission to start the download, the OverallState property of the StorePackageUpdateResult return value has the value Canceled.
The method that you assign to handle Progress notifications is called one time for each step in the download process for each package in this request. The Progress handler receives a StorePackageUpdateStatus argument that provides info about the update package that raised the progress notification.
