 ## Requesting a notification channel
 
+> [!NOTE]
+> The channel-request guidance in this section applies to UWP apps that use [**CreatePushNotificationChannelForApplicationAsync**](/uwp/api/Windows.Networking.PushNotifications.PushNotificationChannelManager#Windows_Networking_PushNotifications_PushNotificationChannelManager_CreatePushNotificationChannelForApplicationAsync_System_String_). If you're building a Windows App SDK desktop app (WinUI 3, WPF, or WinForms), use `PushNotificationManager` instead — see the [Push notifications quickstart](push-quickstart.md).
+
 When an app that is capable of receiving push notifications runs, it must first request a notification channel through the [**CreatePushNotificationChannelForApplicationAsync**](/uwp/api/Windows.Networking.PushNotifications.PushNotificationChannelManager#Windows_Networking_PushNotifications_PushNotificationChannelManager_CreatePushNotificationChannelForApplicationAsync_System_String_). For a full discussion and example code, see [How to request, create, and save a notification channel](request-create-save-notification-channel.md). This API returns a channel URI that is uniquely linked to the calling application and its tile, and through which all notification types can be sent.
 
 After the app has successfully created a channel URI, it sends it to its cloud service, together with any app-specific metadata that should be associated with this URI.
