Public Shared Function Open (appExtensionName As String) As AppExtensionCatalog
The extension namespace name.
A catalog containing the extensions declared with the specified extension namespace name.
For a packaged app to see/enumerate appextensions it must meet at least one of the following criteria:
- Run as MediumIL (or higher)
- Run in an AppContainer and declare a matching appextensionhost
- Run in an AppContainer and have the packageQuery capability
This check is called by AppExtensionCatalog.Open and [AppExtensionCatalog::RequestRemovePackageAsync](/uwp/api/windows.applicationmodel.appextensions.
If you have multiple
<uap3:AppExtensionHost> declarations in your host app, you need to open a separate catalog for each one.
An instance of the PackageCatalog is required to handle the events so keep a reference to it as long as you need to manage your app extensions.
